Albert Johannson's forgotten more than he remembers about his past, but two things he's sure of: he's lived a long, long time, and he doesn't trust anyone, particularly gods. He's not too fond of demons either, particularly the one that shows up in his kitchen looking for help with a supernatural investigation.

Clashing at a crime scene, they uncover an ancient wrought-iron hexagram, a broken relic as old as Solomon. The thing may herald catastrophe unless Albert can mend it—but Albert has yet to grasp just what his special powers really mean . . .
