Bone Deep. The Hollows

First, Alex has a Secret. Then, Alex has another secret. Before he can find a way to unravel either of them, the secrets seem to multiply until he's drowning in an entire ocean of lies and halfway to a Hell of his own design. His friends are gone. His only companion is Death. His soul mate wants nothing to do with him, and those are the high points of Alex's newly finite existence. You might think you have nothing to lose when you're nothing but bones, but you'd be wrong.
Alex was. Caught in a war between rival factions of the underworld, he was meant to be a causality. He was meant to be dead-the kind that sticks-and he will be. But right now? There's something he can't die without. The Hollows, a young adult fantasy series, is best enjoyed in order: Skeleton LakeSkeleton SongDead SeaBone DeepAsh DesertIce Bridge
