Disgraced Return of the Kap's Needle — Renan Bernardo

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.
