Seventeen-year-old Valerie Cardith works in the palace as a human servant. There are a few rules to surviving: don't speak back to a wolf, don't look a wolf in the eye, and take your scent blockers at six sharp every morning.
But when Valerie violates the last rule of the code of survival, she finds herself tied to the Iron King. She learns very early on that the wolves will break her spirit. But only she can decide what she becomes after she shatters. Will she be destroyed? Or will she grow to be the worst thing they fear?
