Underworld - Meg Cabot

Death has her in his grasp. And he's gorgeous.

Seventeen-year-old Pierce Oliviera isn't dead. Not this time. But she's been taken by John Hayden, Lord of the Underworld, to the place between heaven and hell where spirits gather before their final journey. John claims it's to protect her from the Furies, who are hell-bent on vengeance against him. But could he have other reasons for keeping Pierce close? When she learns that the people she loves back home are in mortal danger, can she convince John to release her to save them- or will the price he asks for her freedom be too high?
