Iron Harbor is rocked by storms every summer but this year, it's raining blood. A serial killer stalks the dark urban maze, always two steps ahead of the police. He kills without pattern, without motive, leaving nothing but the dead behind. Masked vigilante Black Tiger is out of his depth. He'd dealt with gangs, crime lords, and supervillains in the past but now he's hunting a foe he can't punch, a shadow that mocks him even as it kills and kills again. The distraction of hot young cop Jordan isn't helping matters, either. Teaming up with a reporter Beth Palmer, who has put together disturbing details about the killer, Black Tiger searches for his elusive prey - unaware that he's being stalked in turn.
