They killed the demons that took their souls, but they couldn't banish the evil within... Salem Vale and Trevor Wickham try to return to their normal lives after they defeat Malice, but when you've been entranced by a demonic rock band and changed into cambions, things get complicated. Salem and Trevor can't get close to anyone-even each other-without wanting to feast on their souls. Then a girl from school turns up dead in the same dumpster Salem woke up in the night she was changed... The girl was obviously a victim of a cambion feeding, but Salem and Trevor already killed all the soul-sucking demons on Earth. Or so they thought. This time, they may be facing an even deadlier foe. Merlin is back, and he'll stop at nothing to get revenge... He sets traps for them in the shadow-ways, plays on their darkest fears, and uses the love of their friends against them. And someone they trust is feeding him secrets. If they don't figure out who, it could spell their deaths. Only one thing can defeat their enemy... Salem is shown the way to defeat Merlin, but will she find the strength to do it? The demon-lust is growing within her, and she can barely control herself. Before long, she may end up killing someone she loves and become a monster worse than the one she wants to destroy. Will Salem be found worthy to vanquish Merlin? Or will she and Trevor succumb to darkness forever?
