The human race has been cast from a dying Earth to wander the stars in a vast fleet of arks. Ahead of the fleet flies the scout ship the *Furious Ocelot*, crewed only by Captain Eryn King and a snarky talking cat. When Eryn's sister disappears during a routine mission, she insists on being part of the crew sent to look for her. What she discovers on Candidate-623 is both terrifying and deadly. When the threat follows her back to the fleet and people start dying, she is tasked with seeking out a legendary recluse who may just hold the key to humanity's survival.
