Searching for the source of the unholy phenomenon -- and to save Cal's sister, Tina -- these unlikely heroes make their way cross country, led by the visions of a lunatic and the fragile song of a blind man. Hidden within ancient burial mounds, a secret paradise may offer the chance of hope, if they can find Tina. But first they must make their way to Chicago to battle a primal monster . . . and the darkness within themselves.
