Radialloy by J. Grace Pennington -- 268 pages
The year is 2320. Andi Lloyd is content with her life as the assistant to her adoptive father, a starship doctor, but her secure world turns upside down when she begins uncovering secrets from her past. When her father mysteriously starts losing his mind, she finds that she can no longer count on him to guide or help her. With mutiny breaking out on the ship, and two factions desperate for a valuable secret she holds, she must race to help her father and herself before time runs out.
Just by reading this book you can tell it is by a young, self-publishing author. But for that it was pretty good. I'm reading her book "Implant" now and like it more than this one.
Radialloy is book one of the Firmament series
