The past is one haunting Jason can't solve.
Now an official member of the lycanthrope pack that had once hired him, the wolf king comes calling with a personal favor. If that wasn't enough, he's met by the messenger of the demon lord that had made his best-friend-turned-lover Adelaide's afterlife a living hell.
The demon Samael is back, continuing his scheme of collecting being associated with death and the underworld. Lex, a hellfire wielding nymph, is his newest target along with his ever present obsession with claiming Adi as his. Jason's taken on ghosts, curses, poltergeists, and demons before but he's never faced someone like Samael before.
Now he must learn how to harness abilities he doesn't understand to take the fight to Samael and sacrifice his world to save his family, the women he loves, and - most of all - Adi. New friends, allies, and lovers join the fray to stop the man that has caused pain, death, and despair for half a millennium. The one they all swore vengeance on for Adelaid's sake.
When the past comes full circle Jason, Adi, Mickie, and Haley must answer one simple question;
Can you kill the boogeyman?
