When Kaylee Cavanaugh screams, someone dies. And Kaylee is about to scream her head off... 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.
But so is someone else.
