SYNOPSIS:
“Death has her in his clutches. She doesn’t want him to let 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 the Furies have discovered that John has broken one of their strictest rules: He revived 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.” 

ABOUT THE AUTHOR:
Meg Cabot was born during the Chinese astrological year of the Fire Horse, a notoriously unlucky sign. After six years as an undergrad at Indiana University, Meg moved to New York City (in the middle of a sanitation worker strike) to pursue a career as an illustrator, at which she failed miserably, forcing her to turn to her favorite hobby–writing novels–for emotional succor.  She is now the author of nearly fifty books for both adults and teens, most notably The Princess Diaries series.
Meg currently divides her time between Key West, Indiana, and New York City with a primary cat (one-eyed Henrietta), various back-up cats, and her husband, who doesn’t know he married a fire horse. Please don’t tell him.
