Kiera awakens to find herself imprisoned. Experiencing horrific nightmares and visions, she slowly realizes that she has been subjected to a series of sinister tests and operations. Now addicted to blood, and in pain, Kiera knows that if she is to survive, she will need to escape from her caged cell. More questions arise: Who is the secretive werewolf visiting her at night - and can she trust him? Where are her friends, and why hasn't Potter come to her rescue, as he promised? With no word from either Luke or Potter, she fears they both might be dead.

With only a chair and a book to comfort her in her cage, can Kiera escape? Even if she does, what will she find on the other side of her prison walls?
