Keir, the blacksmith, has his life turned upside down when he encounters Torin, a quiet woodcutter harboring a dark secret. Intrigued by Torin's request to repair a set of shackles, Keir's curiosity leads him to follow the woodcutter into the woods on a full moon night. What he discovers is not just danger but a shocking transformation as Torin turns into a monster.

But instead of tearing Keir apart, the werewolf reveals a surprising desire: to claim Keir as his mate.

There are more surprises in store for Keir, and a gritty and terrifying truth about the werewolf is soon revealed. On the night of the full moon, there's a part of Torin that is far more wolf than human.
