Her motto is "Life is Death! Death is Life!" Can a warrior trained from birth to kill be trusted?

Crescent is a gene-tweaked mercenary programmed to fight to the death. (Trailer at youtube.com/watch?v=Wz5Pw_tm8Yo) When she's captured by Crater Trueblood, a miner turned soldier, she can't understand his kindness. Maria Medaris, once Crater's girlfriend, has become a ruthless competitor in business and in life. When a murderous band of assassins attack, Crescent, Crater, and Maria escape to a lunar ghost town called Endless Dust. To survive they must do more than navigate the desolate moonscape and battle a persistent band of killers. They must decide what--and who--is truly worth fighting for.

Review

"Readers don't need to have read (the first) Helium-3 book (Crater, 2012) to enjoy the many pleasures of its sequel. ... expertly blending space opera and hard sci-fi, romance, and even mystery..."
- Peter Gutierrez, Booklist Review 
 
"Classic Golden Age science fiction high adventure. It brought back memories of reading Asimov. . . that same sense of wonder. I absolutely loved it."
 -- Michael Scott, New York Times best-selling author, The Secrets of the Immortal Nicholas Flamel series 

"The action is near-constant with the kind of pacing that makes the book difficult to put down... Blending classic action, romance, and intrigue with modern science-fiction informed by the author's background in spacecraft design and engineering, this title is great for any reader looking to go on a unique story beyond Earth's atmosphere."
-- Michael Radon, The US Review of Books

From the Author

Crescent is more than a sequel to Crater. It stands on its own merits. "Crescent" is one of the most interesting characters I've ever written about. The action in this novel never stops. Hang on for a great ride across the dusty moon! Trailer at youtube.com/watch?v=Wz5Pw_tm8Yo
