From #1 New York Times bestselling author Meg Cabot, the dark reimagining of the Persephone myth comes to a thrilling conclusion.

Death has her in his clutches. She doesn't want him to let her go. Seventeen-year-old Pierce Oliviera knew by accepting the love of John Hayden, she'd be forced to live forever in the one place she's always dreaded most: the Underworld. The sacrifice seemed worth it, though, because it meant she could be with the boy she loves.

But now her happiness—and safety—are threatened, all because of the Furies have discovered that John has broken one of their strictest rules: Never revive a human soul.

If the balance between life and death isn't fixed, both the Underworld and Pierce's home back on earth will be wiped away. But there's only one way to restore order. Someone has to die.
