Sanctuary
(Book)

"Prison-guard-in-training Kenzie is taken hostage by the superpowered criminals of the Sanctuary space station--only to have to band together with them when the station is attacked by mysterious creatures"--,Provided by publisher.

A citizen of Omnistellar Concepts, the most powerful corporation in the solar system, Kenzie has trained her entire life for one goal: to become an elite guard on Sanctuary, Omnistellar's space prison for superpowered teens too dangerous for Earth. When a routine drill goes sideways and Kenzie is taken hostage by rioting prisoners, at first, she's confident her commanding officer will secure her freedom. But there's a sinister threat looming, something ancient and evil that has clawed its way into Sanctuary from the vacuum of space. And Kenzie might have to team up with her captors to survive. -- adapted from jacket
