This book takes place in Chicago; specifically Lake Michigan. A ship went down with Egyptian artifacts on board back in the late 1800's. It has finally been discovered and divers are going down to bring up all the treasure.
Unfortunately, people keep coming up dead and people say is is because of a curse..... I really enjoy Heather Graham's series regarding the Krewe of Hunters. She makes me feel like I'm in the city where the story is taking place; so much history of the cities and I really like that.
