In Locksburgh, the rules are simple: stay in the light, fear the dark, and never look the wolf in the eye.

For eighteen years, Rylee has lived as a ghost. Her father's protective lies have built a fortress against the yellow-eyed monster of her nightmares, but the forest is breathing differently.

Now, she is a bridge between a kingdom of iron and a wilderness of spirits. Rylee must uncover the secret of her own forbidden blood before a dangerous past and a primal soul bond consume her whole.

Some secrets are meant to be buried. Others are meant to burn.
