"Run, lil rabbit, 'fore Wolf tears you apart."

Twelve years ago, Ember Cutler obeyed her father and ran; but the girl who disappeared into the desert was not the same girl who came out. When her oldest brother appears in her clinic at the Vault and abducts her at gunpoint, he expects to find his little sister, Ember, but instead finds a grief-stricken, broken Bones.

Taken by Wolf and his crew of deadly bounty hunters, Bones struggles to prove her innocence and stay present while Wolf struggles to reconcile the fiery little girl he remembers, the manipulative killer he thought he hunted, and the hollow-eyed woman he captured.

With her past and present identities colliding, Bones tries to untangle who she is now from her trauma with help from Mac and her crew. But the gods have taken notice of her-and her potential-and the line between ally and enemy begins to blur.

When her magic begins to change in a way that threatens to alter the entire world, Bones is forced to decide who she wants to be and who holds the scales.
