Haunted by the ghosts of his father and grandfather, he learns that the woman he rescued is in fact an Innocent, the physical embodiment of hope. As it turns out, seeing dead people is the least of James' worries. It's the trolls, goblins, vampires, and other assorted creepy-crawlies that make being dead a living nightmare.
When a Madness Demon kidnaps the Innocent to sacrifice at the Blood Moon ritual, it's up to James and an odd assortment of Otherworld companions to rescue her. If they fail, humanity will be without hope for the next thousand years.
To succeed, James must first battle his own inner demons, and come to grips with who and what he has become. After all, when you're dead, wishing you were is kind of counter-productive.
