Inferno

In Inferno, the fourth novel in the bestselling Chronicles of Nick series from #1 New York Times bestselling author Sherrilyn Kenyon, the heat is on, and a new threat to humanity has risen . . .
Nick has his driver's license and he's not afraid to use it. But turning sixteen isn't what he thought it would be. While other boys his age are worried about prom dates and applying for college, Nick is neck deep in enemies out to stop him from living another day. No longer sure if he can trust anyone, his only ally seems to be the one person he's been told will ultimately kill him.
But life spent serving the undead is anything except ordinary. And those out to get him have summoned an ancient force so powerful even the gods fear it. As Nick learns to command and control the elements, the one he must master in order to combat his latest foe is the one most likely to destroy him. As the old proverb goes, fire knows nothing of mercy, and if Nick is to survive this latest round, he will have to sacrifice a part of himself. However, the best sacrifice is seldom the sanest move. Sometimes it's the one that leaves your enemies confused.
And sometimes, you have to trust your enemy to save your friends. But what do you do when that enemy is you?
