Prometheus Outbound by Steve Ruskin

"It's like the sequence at the end of Aliens, where Sigourney Weaver gets in her Power Loader exoskeleton... only make that the whole movie."

– D.J. Butler, Dragon Award Winning Author

Climbing Olympus by Kevin J. Anderson

"I would recommend this book to to anyone who enjoys science fiction. The thing about Kevin Anderson is that he does not bring myth and magic in to his novels so they all portray a conceivable future." – Amazon Review

Neodymium Exodus by Jen Finelli, MD

"The fascinating characters matched with inventive biological details makes this an adventure that's sure to enthrall."

– Publishers Weekly

Writers of the Future Volume 36 by David Farland

"This hefty, competent anthology showcases 12 consistently solid short stories, each accompanied by a full-color illustration. A worthwhile survey of new voices in the field."

– Publishers Weekly

Queen of Sidonia by Richard Fox

"This has all the elements of a mystery novel. There is danger at every turn. There is royal intrigue. A real cliffhanger awaits at the ending."

– Amazon review

The Altrean Legacy by Nick Thacker

"This book is awesome and packed with action and suspense. I will definitely be reading more of this series. Lovers of James Rollins should definitely read this."

– Reader review

Warrior Integration by David Hallquist

"I enjoyed this story from page one. It progressed rapidly and in directions I never foresaw. Very suspenseful and full of action. Great story!"

– Amazon Review

The Fall of Rho-Torkis by Tim C. Taylor

"There is a nice amount of back story and character development for all main characters, and they come across as real people, with real strengths and weaknesses coming through. Their struggles are very realistically portrayed, and it really helps immerse you in the story. These characters are definitely a strength, and are as good as any in sci-fi today."

– The Bookwyrm Speaks

Legend by Christopher Woods

"This book reeled me in, and had me not wanting to put it down. 5-stars!"

– Reader Review

The Cassidy Chronicles by Adam Gaffen

"The writer keeps the action going as the women move from one event to the other. There are many supporting characters adding exciting dimensions to the narrative and the principals prove to be decisive, bright, and resourceful. The new America readers find superimposed on the world created by the writer is disturbing yet interesting, contributing to the adventure. I'm looking forward to discovering what happens."

Zero DRM. There's no DRM on any of our books. None. Why? For one, we don't believe DRM actually stops people from sharing what they want to share. Second, and most importantly, we don't believe we should be treating our customers as criminals. So go ahead and put these on your tablets, Kindles and smartphones, but if a friend wants to read the bundle, please have them buy one for themselves. With pay-what-you-want, we believe there's a price for everyone. Or better yet, buy one for them as a gift. Help support indie authors!

Support nonprofits. Best of all, you can also give a portion of the proceeds from each bundle to charity. To learn more about these charities and those they help, click the "Learn More" link next the charities when you purchase.

Easy delivery. It's super convenient to get these ebooks onto your reader of choice—just download and sync. Better yet, if you have a Kindle or Kindle-enabled tablet or smartphone, we can send the books directly to your device. No computer required.
