Cracking the case will cost Mac the last of his humanity. Walking away means Constance loses her son.

Detective Macmillan has a taste for bad girls, but his last lover took the cake—and his soul. Now half-demon, Mac’s lost his friends, his job, and his freedom.

Constance is a vampire trapped inside the Castle prison. Her adopted child has been kidnapped, and she turns to Mac for help. The trail leads them deep into the dungeon, where the stakes are beyond Mac’s worst fears—beyond even death itself.

Fiery, vulnerable Constance will do anything for those she loves, including Mac. And he’ll be damned if he turns his back on her—and a demon forever if he doesn’t.

Welcome to the Castle. The price of admission is your soul.
