After settling a fragile truce between the vampires, werewolves and witches, the last thing Jessica wants to do is face the demons head on. But when the Prince of Hell kidnapped her brother, he set into motion a chain of events that even Jessica doesn't have the power to stop.
Now, Jessica must go into battle again. But Hell is a whole new beast -- new rules, more dangerous demons, and an entirely foreign realm. And when Jessica is dropped into the Underworld too soon, without protection or the help of her friends, she must figure out just how powerful she can be... or she will never make it out alive.
