1898: Bound for Chicago, the freighter Jerry McGuen, carrying the ill-gotten sarcophagus of an Egyptian sorcerer, goes down in Lake Michigan, taking with it every man aboard. Now: A veteran diver and "ghost ship" expert is exploring the wreck for a documentary and dies inexplicably. 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.
