Clara Crossman is an assassin, but her targets aren't even close to human. She hunts down the nastiest things that the Netherworld has to offer. Bound by an unbreakable promise to help one of them, Clara knows she's in too deep. After all, she doesn't even know what sort of Netherworld creature he is. Making a deal with him was a big mistake.

How many different ways will she have to pay for that mistake before there is nothing left to give?
