Monsters walk the streets of Chicago. So do werewolves. Violence swirls around a vulnerable street waif caught between sorcery and madness. Vicious murders on Chicago's near north side pull Vincent Thiess out of retirement as a police profiler. He must untangle conflicting threads from the Church, the FBI, medieval folklore and his own tortured past. Behind the facade of an old Italian neighborhood, do werewolves really prowl? As Vincent struggles to separate reality from nightmare, ancient truths from modern deception, he must protect his family and solve the mystery of the young woman at the center of it all-and keep himself from falling desperately in love.
