Joe Golem: The Conjurors (Joe Golem: The Conjurors #3)

Long before Simon Church hunted witches, that mission belonged to the golem. And the deeper the golem ventures into the tunnels beneath the Drowning City, the deeper he delves into his past. But once Dr. Cocteau reveals the true intent behind his search for the Pentajulum, and the role he expects Felix and Molly to play in his plan, the entire city's future will be in jeopardy.
