Meet Kaylee Cavanaugh, typical teenager, dealing with normal day to day high school experiences. Normal, that is, if you don't count the terrifying hidden worlds with reapers, hellions, and countless other mythical monsters mixed in. Kaylee Cavanaugh, typical teenager, and banshee.

When Kaylee Cavanaugh screams, someone dies.

So when teen pop star Eden croaks onstage and Kaylee doesn't wail, she knows something is dead wrong. She can't cry for someone who has no soul.

The last thing Kaylee needs right now is to be skipping school, breaking her dad's ironclad curfew and putting her too-hot-to-be-real boyfriend's loyalty to the test. But starry-eyed teens are trading their souls: a flickering lifetime of fame and fortune in exchange for eternity in the Netherworld--a consequence they can't possibly understand.

Kaylee can't let that happen, even if trying to save their souls means putting her own at risk....

Kaylee has one addiction: her very hot, very popular boyfriend, Nash. A banshee like Kaylee, Nash understands her like no one else. Nothing can come between them.

Until something does.

Demon breath. No, not the toothpaste-challenged kind. The Netherworld kind. The kind that really can kill you. Somehow the super-addictive substance has made its way to the human world. But how? Kaylee and Nash have to cut off the source and protect their friends--one of whom is already hooked.

And so is someone else...
