Updating Book Trailers

Over the last few months, I’ve been releasing new editions of several of my novels. Some of these had video trailers associated with them. Last month, I discussed updating the trailer for The Astronomer’s Crypt. That was a really premium cinematic trailer and the only things that went out of date were the cover and information about where the book was available. I did need expert help to fix those elements because they were so well done, but most of the trailer is just the same as it was back when it was first released.

The very first book trailer I ever made was one for my novel Vampires of the Scarlet Order. I was fortunate enough to have a batch of beautiful interior illustrations by Steven Gilberts to work with. One of my neighbors came over and played music on guitar and I mixed that with audio of myself reading the book description. Since the illustrations were black and white, I used filters in my video editing software to give the images some film stutter and scratches, so the whole thing looked like an old film. It was pretty cool. The only thing I didn’t like was that the audio was a little muddy because I didn’t have a great microphone and it was recorded on tape rather than digitally. Two years ago, I dusted off the old trailer and gave it a new ending because the information about the book’s availability had become outdated, but I knew the whole trailer could use a thorough overhaul.

Screenshot from the new Vampires of the Scarlet Order trailer.

This year, when Chaz Kemp did a whole new cover for Vampires of the Scarlet Order, I saw that as a great opportunity to redo the trailer. As part of his work, he sent me individual illustrations of the characters. I was able to apply filters in Adobe Photoshop to photographs I have of real locations from the novel to make them look like paintings. I then placed the characters over them. Once that was done, I read the updated book description and found some cool music that matched the mood from Keven MacLeod at http://incompetech.com. Although all the images are stills, I think the trailer has a neat animated-movie like vibe.

Once I made this trailer, I realized I also wanted to update my trailer for The Solar Sea. The original version of that trailer featured illustrations Laura Givens had made for a website promoting the novel. Also, I used her illustration of the novel’s solar sail to create an old-fashioned animation of the solar sail entering orbit around Jupiter. The only thing I didn’t like about the original trailer was that the music was a little short for the video length and I didn’t narrate it. I used intertitle cards like one might find in a silent movie. This time I recorded narration and I found a really dramatic piece of music that highlighted the narration.

I find trailers like this fun to make, but they do take time to get right. The tech required is pretty simple. I used Windows Live Movie Maker for the first video. I used the OpenShot Video Editor for the second one. This was necessary when I found Windows Live Movie Maker wouldn’t import the Movie Maker files with my animation from a decade ago. OpenShot is available at http://openshot.org

As for creating images for this kind of trailer, the best advice I can give is to get on good terms with your cover artist or an artist who can create art to match the flavor and style of your book. Make sure you’ve paid your artist fairly for their work. Recording narration is like any skill. It takes practice. Write your script. Practice reading it at the microphone and record a few takes. It’s easy to flub a word or miss the sound of something like a motorcycle passing the house or a lawnmower next door.

Finally, have fun! I had a blast creating these videos and I hope they’re fun to watch. Of course, I hope they also tempt you to learn a little more about the novels. If you would like to, drop by http://www.davidleesummers.com

The Space Pirates’ Legacy

The annual Smashwords Summer/Winter Sale is underway. It gets its name because where I live in the northern hemisphere, readers are loading up their e-readers for great beach reading and vacations. In the southern hemisphere, it’s the middle of winter and people are spending time in a warm and cozy place reading. All of Hadrosaur’s titles are available at deep discounts this month and I’ll be highlighting them all month long here at the Web Journal. If you’re looking for a specific title, you don’t have to wait for me to highlight it, just visit http://www.hadrosaur.com/bookstore.php and click on the book you’re interested in. On its page is a link to Smashwords if its available there. The coupon codes for these discounts are automatically applied at checkout. One of the things I love about Smashwords is that they provide ebooks in all popular formats and they’re DRM free, so you can download them to your favorite device.

Today, I’m getting ready for the release of the twenty-fifth anniversary edition of my very first novel, The Pirates of Sufiro. It originally started a trilogy of novels, but as I thought about the series, I realized it really needed to be the second novel. Today, I share the current first novel of the Space Pirates’ Legacy series, Firebrandt’s Legacy, along with The Solar Sea, which is a prequel that tells the story of how humans came to be part of the galactic civilization I envision in those novels.


The Solar Sea

In The Solar Sea, whales around the world changed their songs the day scientists announced the discovery of powerful new particles around Saturn’s largest moon which could solve Earth’s energy needs. The Quinn Corporation rushes to build a solar sail space craft to unlock the secrets of these strange new particles. They gather the best and brightest to pilot the ship: Jonathan Jefferson, an aging astronaut known as the last man on Mars; Natalie Freeman, a distinguished Navy captain; Myra Lee, a biologist who believes the whales are communicating with Saturn; and John O’Connell, the technician who first discovered the particles. Charting the course is the mysterious Pilot who seems determined to keep secrets from the rest of the crew. Together they make a grand tour of the solar system and discover not only wonders but dangers beyond their imagination.

T. Jackson King, the author of Battlestar and Star Glory says, “This story follows the private space industry exploration of the Moon and becomes a kind of Voyage of the Beagle as the solar sail ship Aristarchus visits Mars, Jupiter, then Saturn and its giant moon Titan … Highly enjoyable read. Highly recommended.”

Firebrandt’s Legacy

In Firebrandt’s Legacy, Ellison Firebrandt fights the good fight for Earth. Under a letter of marque, he raids the ships of Earth’s opponents, slowing down their progress and ability to compete with the home system. On the planet Epsilon Indi 2, he rescues a woman named Suki Mori from a drug lord, only to find she isn’t so happy about living a pirate’s life. However, when the captain finds a new engine that will make him the most successful pirate of all, Suki is the only one who can make it work. Now Firebrandt must find a way to keep his crew fed and his ship supplied while relying on a woman who barely trusts him and while every government in the galaxy hunts him to get the engine back!

Midwest Book Review says, “A grand space opera filled with high adventure from cover to cover, Firebrandt’s Legacy is highly recommended.”

LightSail 2 – One Year After Launch

This past Thursday marked the one-year anniversary of LightSail 2’s launch into orbit. LightSail 2 is a crowdfunded solar sail project managed by the Planetary Society and it’s the first craft propelled entirely by sunlight. The Planetary Society hosted a webinar to celebrate the event. Planetary Society CEO Bill Nye, Chief Operating Officer Jennifer Vaughn, Program Manager Dave Spencer, and Project Manager Bruce Betts all spoke. The presentation was moderated by Planetary Radio host Mat Kaplan. I am pleased to have been one of the mission funders and I was delighted to have had an opportunity to attend the webinar live. I gather the presentation will be viewable soon at https://www.planetary.org/multimedia/planetary-tv/. I found the presentation fascinating and I took three pages of notes. I’ll touch on a few highlights below and in Tuesday’s blog post, but if you’re interested in this project, be sure to check out the full video at the link above. You can learn more about the Planetary Society by visiting http://www.planetary.org.

Screen shot of the live webinar featuring Bill Nye, Dave Spencer, Mat Kaplan, Jennifer Vaughn, and Bruce Betts

The most exciting news from the webinar is that LightSail 2 is still flying one year after launch. It was placed into an orbit about 720 kilometers above the Earth’s surface, which is still low enough to have a very small amount of atmospheric drag. Despite that, the spacecraft has only lost about 10 km of altitude over the course of a year. It’s not certain how long it will be before it de-orbits, but current estimates say LightSail 2 could continue its mission for another year.

Bill Nye opened the presentation by noting it was 17th century astronomer Johannes Kepler who first speculated on the possibility of solar sails after observing the comet that would ultimately be known as Comet Halley. He reasoned that whatever force from the sun could produce the comet’s tail could propel a sailing vessel to other planets. The specific particle that can be used to propel a solar sail is the humble photon. Light has momentum and that momentum can be transferred to the sail for motion.

LightSail 2 has been able to perform so well because it can be turned like a sailboat’s sail. In this case, the craft is turned by momentum wheels aboard the ship. Momentum wheels are just gyroscopes, but tradition suggests that the word “gyroscope” is used principally when applied to navigation. When LightSail 2 is in a position to get a boost from sunlight, it turns so the sail catches all the light. When the light pressure would work against the sail, the craft turns 90 degrees so it presents the sun with the least amount of surface to push against.

Many great photos were shared during the webinar. My favorite was this one showing LightSail 2 over the Nile and the Red Sea. As you’ll notice, there’s a thin blue line at the Earth’s left edge. That’s our atmosphere, which looks very thin and fragile. I also imagine measuring the spectrum of that thin film on a planet in some distant stellar system from a telescope in our solar system. It’s a real technical challenge, but it looks like we may be getting close to a point where we could do that. This is something we’ll need to do in order to determine whether or not an exoplanet is potentially habitable.

The Solar Sea

One of the things that makes all of this personally exciting is that I first joined the Planetary Society when I was in high school as a result of a letter sent to Star Trek fan clubs by Gene Roddenberry. I first learned of the Society’s interest to make solar sails a reality in the society’s newsletter, The Planetary Report. The idea caught my imagination and in high school, I started to write a novel called The Solar Sea. I didn’t complete it then, but the idea stayed with me and I made several attempts until I wrote a version that pleased me. That version was published in 2008 and you can learn more about it at: http://davidleesummers.com/solar_sea.html

Radio Interviews

One of the difficult things about the current COVID-19 crisis has been the cancellation or postponing of events all around the country. Last weekend, I had been scheduled to attend El Paso Comic Con. Hopefully, circumstances will allow me to make the rescheduled event in October. These events are vitally important to independent authors and publishers. They’re my opportunity to meet you face to face and talk to you about the books I’ve written and those written by others that I’ve felt passionate enough about to publish.

A little over a week ago, I made a pleasant discovery. Here at the web journal, I’ve promoted interviews I’ve done on Lynn Moorer’s show, “All About Books” at Las Cruces Community Radio Station KTAL-LP 101.5 FM. Thanks to the internet, you didn’t have to be in Las Cruces to hear these shows, you could stream them as they aired. Unfortunately, you did have to listen to them at the time they aired. I have now discovered that Radio Que Tal has archived many of its shows and you can now listen to two of my interviews at your leisure. Lynn asks me about the books and has me give a couple of readings. It may not be quite as good as meeting me face to face at a convention, but it will give you a taste and best of all, you can listen on your schedule!

The older interview featured on line is for my steampunk novel Owl Riders. This novel is the fourth in my Clockwork Legion steampunk series, but it’s set about a decade after the other books in the series, so it stands very much alone. Taking place in 1885 with protagonists Fatemeh and Ramon Morales settled in New Orleans, Ramon, now a U. S. Assistant Attorney, is called upon to settle a dispute between the Chiracahua Apache and the U. S. Army over a sliver of land in southern Arizona.  Healer and pharmacist Fatemeh is kidnapped by Hamid Farzan, a Persian merchant to whom she was originally betrothed.  Fatemeh’s and Ramon’s daughter Alethea uses her intelligence and resourcefulness to help rescue her mother. You can listen to the interview at: http://www.lccommunityradio.org/archives/all-about-books-david-lee-summers

In October, Lynn spoke with me about my science fiction adventure, The Solar Sea, the first in a series, about a solar sail ship, the Aristarchus, which travels to Mars, Jupiter, and Saturn, battling hazards in space amidst conflict among crew members.  As the fascinating story develops, readers learn how whales and their songs fit into the universe and into the hierarchy of beings. You can listen to this interview at: http://www.lccommunityradio.org/archives/all-about-books-david-lee-summers-author-of-the-solar-sea

I’ll be visiting with Lynn next month to talk about the next book in this universe, Firebrandt’s Legacy. That interview is scheduled for May 22 at 12:30pm Mountain Daylight Time. Hopefully I’ll be able to share an archive link soon after the interview airs, but you can mark your calendars and listen live at: http://www.lccommunityradio.org/listen.html

Another thing I’m pleased to announce is that my website http://www.davidleesummers.com now lives on a devoted web server. Until about a week ago, I relied on web forwarding from the name registrar to point to my site at the internet service provider. Unfortunately, the forwarding wasn’t very reliable and there were times it just didn’t work, making it look like my website was down. Links to my site throughout the web journal should work much better now.

Explore New Worlds from Home

In my last post, I mentioned how fortunate I am to have a fairly secure income during this difficult time of the COVID-19 pandemic. Many people are finding themselves unemployed or under employed. Fortunate as I am, it’s likely our family will also be affected by current events. I’m waiting to hear whether events I attend to promote my writing will be going forward. If not, this could result in a loss of sales for my books. What’s more, my wife performs bookkeeping duties for many small service-industry businesses. So far, these businesses have continued to operate, but some have had to limit their operations and depending on how long we’re asked to practice social distancing, may have to shut down for a time.

This crisis also comes at a time when my youngest daughter is preparing to graduate from high school and go to university. She’s been busy working on assignments at home, but we have had to defer a visit to her future school because of current events.

So far, my writing and editing work is keeping me busy, but I know this enforced period of isolation is hard on many people. That’s one of the reasons I’m participating in the “Authors Give Back” event at Smashwords. On Saturday, I shared two books I’m giving away for free. Because I do have family responsibilities, I can’t afford to give away all of my books, but I can offer deep discounts on two additional titles and give you a chance to explore the solar system and the galaxy in the process.

The first book I’m offering at 60% off the cover price is my novel The Solar Sea. In the novel, whales around the world changed their songs the day scientists announced the discovery of powerful new particles around Saturn’s largest moon which could solve Earth’s energy needs. The Quinn Corporation rushes to build a solar sail space craft to unlock the secrets of these strange new particles. They gather the best and brightest to pilot the ship: Jonathan Jefferson, an aging astronaut known as the last man on Mars; Natalie Freeman, a distinguished Navy captain; Myra Lee, a biologist who believes the whales are communicating with Saturn; and John O’Connell, the technician who first discovered the particles. Charting the course is the mysterious Pilot who seems determined to keep secrets from the rest of the crew. Together they make a grand tour of the solar system and discover not only wonders but dangers beyond their imagination.

In the novel, I use my experience as a professional astronomer to bring the solar system to life for the readers. You can get The Solar Sea for 60% off the cover price at: https://www.smashwords.com/books/view/805692

The second book I’m offering at a discount is Firebrandt’s Legacy. In this book, Ellison Firebrandt fights the good fight for Earth. Under a letter of marque, he raids the ships of Earth’s opponents, slowing down their progress and ability to compete with the home system. On the planet Epsilon Indi 2, he rescues a woman named Suki Mori from a drug lord, only to find she isn’t so happy about living a pirate’s life. However, when the captain finds a new engine that will make him the most successful pirate of all, Suki is the only one who can make it work. Now Firebrandt must find a way to keep his crew fed and his ship supplied while relying on a woman who barely trusts him and while every government in the galaxy hunts him to get the engine back!

This book sets the stage for The Pirates of Sufiro, which I’m working on right now, along with the rest of the Space Pirates’ Legacy series. In the opening chapter, Captain Firebrandt attacks a ship and discovers a whole cargo hold of … toilet paper. It’s just a small moment, but who knew that would be a thing?

Christmas in Space

Last year was the 50th anniversary of the first celebration of Christmas in space. This happened during the Apollo 8 mission commanded by Frank Borman with James Lovell Jr. serving as command module pilot and William Anders serving as lunar module pilot. On Christmas Eve 1968, Apollo 8 entered orbit around the Moon. During the mission, they took the famous Earthrise photo, showing the Earth rising over the Lunar horizon. Ten hours later, they took turns during a transmission to Earth to read the opening verses of Genesis. Borman concluded the transmission by saying, “And from the crew of Apollo 8, we close with good night, good luck, a merry Christmas, and God bless all of you, all of you on the good Earth.” During a transmission four hours later, James Lovell reported, “Please be informed there IS a Santa Claus.”

After he retired from NASA, Borman lived for a time to Las Cruces, New Mexico and was still living there when I moved to town in 1995.

In December 1993, Mission Specialist Jeffrey Hoffman celebrated Hanukkah on the Space Shuttle Discovery. He brought a dreidel and a travel menorah and spoke about Hanukkah during a live television broadcast. During the mission, the shuttle captured the Hubble Space Telescope, brought it into the shuttle bay and performed a full service of the instrument over the course of five space walks.

Although we have never achieved the science fictional promise of cities in space, we have achieved more regular habitation of space in the years since Apollo 8 through the International Space Station. Christmas is regularly celebrated there and its fun to see stockings hung on the station and astronauts with fuzzy, red hats. That said, Americans aren’t the only crew members. Russians who serve aboard the ISS often emphasize New Year celebrations over Christmas. When they do celebrate Christmas, many celebrate Orthodox Christmas in January.

When I wrote my novel The Solar Sea, it seemed only natural that people would make an effort to celebrate those holidays that were special to them. December arrives as the solar sail Aristarchus travels to Mars. The character Vanda Berko finds special meaning in the menorah’s light while traveling through the darkness of space. The ship’s cook brings a small tree aboard the ship and the crew decorate it and sing carols on Christmas morning.

James Lovell, the astronaut who declared “there IS a Santa Claus” on Apollo 8 would go on to become commander of the ill-fated Apollo 13. When the Aristarchus crew gets into trouble, they cheer themselves by remembering that dire as that early mission was, Lovell helped to bring the crew home safely.

After NaNo

I’m sorry to say I didn’t get a chance to participate in this year’s National Novel Writing Month. My daughter did give it a try and I’m proud that she managed to make good progress on a project she’s working on. For those who don’t know about the National Novel Writing Month, every November writers are challenged to write 50,000 words in a month. Because I’m in the midst of commissioning two instruments at Kitt Peak National Observatory, I didn’t think I could commit to that amount of writing during November this year. However, I have participated twice before and both of my NaNoWriMo novels ultimately became published works.

While 50,000 words is a good amount of a novel, it’s shorter than what most genre publishers are looking for. Some publishers are happy to see young adult books around this length, but even they tend to want at least slightly longer. Also, the organizers of NaNoWriMo encourage authors not to spend time revising their works during the month. The goal is just to get 50,000 new words down on the page. So, how do you go from 50,000 unedited words to a novel you’re willing to submit to a publisher?

I first learned about NaNoWriMo from Jackie Druga, who owned LBF Books, which had just purchased my novels Vampires of the Scarlet Order, The Pirates of Sufiro, and Children of the Old Stars. She challenged me to try my hand at writing a novel in a month. I decided it was time to actually write a novel I’d started twice before, but gave up on called The Solar Sea. The reason I’d given up on this novel twice before is that I didn’t know quite what it wanted to be. Was it an adventure novel? Was there more of a suspense element? Should it be for adults? The 50,000 word length and being a parent of two young daughters inspired me to approach this new start as a young adult novel. I’d thought about it so much over the previous fifteen years, I had really clear pictures of the characters, so writing it was easy. When I got to the end of the month, I had a more-or-less complete novel. It needed spelling and grammar cleaned up. It needed details fleshed out. I ran it by three or four beta readers. I even read it aloud to my daughters and was pleased to see how much the story held them, but even at a young age, they pointed out places where they wanted more. By the time all was said and done, I had a 65,000 word novel and LBF said they were willing to publish it. If you want to see the result, you can learn more about the current edition at: http://www.davidleesummers.com/solar_sea.html

Because things had gone so well, Jackie encouraged me to participate in NaNoWriMo again the next year. This time, my project was much less defined. I knew I wanted to write a prequel to my novel Vampires of the Scarlet Order and I had a rough idea of what the story would be. I set out on the journey to create the book that would ultimately become Dragon’s Fall: Rise of the Scarlet Order. I did finish 50,000 words, but I was left with the feeling that I had far from a complete novel. I liked the opening, but felt like the book was beginning to meander toward the end. I also didn’t feel like it had a good focus. In this case, I set the novel aside until I had some idea of what to do with it.

I believe about two years passed. I made a few half-hearted attempts at editing, but was never quite sure what the book was missing. By that time, LBF Books had been purchased by Lachesis Publishing and LeeAnn Lessard approached me with the idea of writing five vampire novellas with erotic overtones. It occurred to me that my NaNoWriMo attempt to could be adapted into three of those. As I thought about what the other two novellas could be, I found a new opening that gave the whole project focus and an overarching theme. With that in mind, I was able to find an ending that became the final novella. Ultimately, those five novellas were published under one cover and called Dragon’s Fall: Rise of the Scarlet Order. Each of the novellas is a part of the story set in a different time period. As the story evolves, the vampires of the story become romantically involved. In this case, it helped to give myself some distance from the original creation and to get some input that gave me a slightly different approach. By the time I fleshed out the middle and added a new beginning and end, I had a 94,000-word novel. If you’d like to learn more about this novel, visit http://www.davidleesummers.com/dragons_fall.html

To all of you who made good progress on a project this year during NaNoWriMo, I salute you! I wish you the best as you polish your work and help it find its final form.

Successful Solar Sailing

The Planetary Society’s LightSail 2 spacecraft launched into orbit on June 25, 2019 and deployed its 32-square meter sails almost a month later on July 23. In the time since sail deployment, it raised its orbit some seven kilometers. Here we see a great shot of the LightSail 2 over Australia.

In 1619, astronomer Johannes Kepler noticed that comet tails always point away from the sun and realized that some solar force must produce that effect. Two centuries later, in 1862, James Clerk Maxwell suggested that light has momentum and it was finally demonstrated in 1900. The goal of the LightSail 2 mission was to show that momentum from light could propel a spacecraft. The process of solar sailing is not unlike sailing on the water, only in space, gravity acts like water currents while light acts like wind. As with a sail at sea, the sails must be turned in flight to take the best advantage of the “wind” while the ship moves on the “current.” LightSail 2 accomplishes this via internal reaction wheels. The gif below shows how the sail is turned to take the best advantage of sunlight and raise its orbit.

Josh Spradling / The Planetary Society

The following graph shows the elevation of LightSail2 over the course of the mission. The apogee is the highest point in orbit, the perigee is the lowest point. At LightSail2’s elevation, there are two forces working on the sail besides gravity. The first is light pressure from the sun. The other is atmospheric drag from the Earth. Even though LightSail 2 is in a relatively high orbit, it’s still in the most tenuous parts of the upper atmosphere. The upshot is that the apogee increases because of light pressure, but the perigee decreases because of atmospheric drag. That noted, LightSail 2 has accomplished the mission it set out to do, demonstrate that light can propel a spacecraft.

You can keep up to date with the LightSail mission and visit their mission control page by going to http://www.planetary.org/explore/projects/lightsail-solar-sailing/#the-lightsail-2-mission.

It’s worth noting this is a technology in its infancy. That said, with the lessons learned from this mission, there’s promise that solar sails could be used for small unmanned probes in the not-too-distant future, or perhaps they could be used to deflect dangerous asteroids, especially if caught early enough that they only need a small nudge.

In the long run, with much more development and technical innovation, I would like to think solar sails could be used to propel humans across the solar system as I imagine in my novel The Solar Sea. In a little under a week, on Friday October 11, Lynn Moorer will interview me about the novel on her radio show from 12:30-1:00 pm mountain daylight time. If you’re in Las Cruces, you can tune in to 101.5 FM on your radio dial. If you aren’t in Las Cruces, or just don’t listen to shows on the radio, you can stream the show at  https://www.lccommunityradio.org/stream.html. It looks like KTAL Community Radio is building up their archive of past shows, so I’m hoping I can share these interviews with you soon. If you want to read the book before the interview, you can find all the places it’s available by visiting http://www.davidleesummers.com/solar_sea.html.

Celebrating the Future

Early in the morning of June 25, the Planetary Society’s LightSail 2 mission launched aboard a SpaceX Falcon Heavy rocket. Actual deployment of the sail is set for today. These are great accomplishments to celebrate. On a more personal note, my novel Firebrandt’s Legacy received a wonderful review from Midwest Book Review. The reviewer says Firebrandt’s Legacy is “A rip-roaring space adventure!”

Also underway is the annual Smashwords Summer/Winter Sale. It gets its name because where I live in the northern hemisphere, readers are loading up their e-readers for great beach reading and vacations. In the southern hemisphere, it’s the middle of winter where people are spending time in a warm and cozy place reading. So, to celebrate the successful launch of LightSail 2 and a good review in Midwest Book Review, my novels The Solar Sea and Firebrandt’s Legacy are on sale at Smashwords for just $1.00 each this month. Keep reading for the details.


In The Solar Sea, whales around the world changed their songs the day scientists announced the discovery of powerful new particles around Saturn’s largest moon which could solve Earth’s energy needs. The Quinn Corporation rushes to build a solar sail space craft to unlock the secrets of these strange new particles. They gather the best and brightest to pilot the ship: Jonathan Jefferson, an aging astronaut known as the last man on Mars; Natalie Freeman, a distinguished Navy captain; Myra Lee, a biologist who believes the whales are communicating with Saturn; and John O’Connell, the technician who first discovered the particles. Charting the course is the mysterious Pilot who seems determined to keep secrets from the rest of the crew. Together they make a grand tour of the solar system and discover not only wonders but dangers beyond their imagination.

T. Jackson King, the author of Battlestar and Star Glory says, “This story follows the private space industry exploration of the Moon and becomes a kind of Voyage of the Beagle as the solar sail ship Aristarchus visits Mars, Jupiter, then Saturn and its giant moon Titan … Highly enjoyable read. Highly recommended.”

In Firebrandt’s Legacy, Ellison Firebrandt fights the good fight for Earth. Under a letter of marque, he raids the ships of Earth’s opponents, slowing down their progress and ability to compete with the home system. On the planet Epsilon Indi 2, he rescues a woman named Suki Mori from a drug lord, only to find she isn’t so happy about living a pirate’s life. However, when the captain finds a new engine that will make him the most successful pirate of all, Suki is the only one who can make it work. Now Firebrandt must find a way to keep his crew fed and his ship supplied while relying on a woman who barely trusts him and while every government in the galaxy hunts him to get the engine back!

Midwest Book Review says, “A grand space opera filled with high adventure from cover to cover, Firebrandt’s Legacy is highly recommended.”
