In 2144 AD, the generation ship Kap's Needle left Earth to settle a new world. It all went wrong. Now, two years into a desperate return trip, the ship's biospheres are collapsing and oxygen is nearly depleted. Life Support Manager Reva is now little more than a tax collector, deciding who gets to breathe. When Captain Horvat launches a corruption purge to cover his own failures, Reva knows she's next. To protect her son, she must do the unthinkable: trust First Officer Torres, the woman who ruined her life, and help bring down the captain no matter how many innocent lives it costs. BONUS CONTENT includes two short stories by the author: "A Lifeline of Silk" and "Callis Praedictionem."
