Kathryn Beck's life was forever altered when she was recruited out of college into an elite, top-secret organization whose members possess supernatural weapons and which takes on challenges that no other group is equipped to handle. But, her next mission in Alaska turns her world upside down all over again, when she's framed for a terrible crime and tossed helplessly into prison.

Severed from her team and unable to use her supernatural gifts, Kathryn must navigate the cruel and arbitrary caprices of the criminal justice system as she struggles to free herself, while forming alliances with other inmates and battling a sinister conspiracy behind the operation of the remote prison-a conspiracy that threatens to ensnare not only her, but dozens of other innocent women caught in its clutches.

In a place where enemies become friends and friends become monsters, Kathryn will face her biggest challenge yet.
