1898: Bound for Chicago, the freighter Jerry McGuen goes down in Lake Michigan, taking with it every man aboard. But what other fate could befall a vessel carrying the ill-gotten sarcophagus of an Egyptian sorcerer? Now: A veteran diver and “ghost ship” expert is exploring the legendary wreck for a documentary. He dies inexplicably inside the freighter’s main saloon. Then another diver is killed and panicked rumors rise like bubbles from the lake: ancient demons have awakened below! The expedition’s beleaguered financier calls paranormal investigator Katya Sokolov to Chicago to save the film — and perhaps some innocent lives. Along with media forensics guru Will Chan, Kat plumbs the depths of an evil that may date back to the time of the Pharaohs.
