My Best Friend's Exorcism: A Novel

From the New York Times best-selling author of The Southern Book Club's Guide to Slaying Vampires comes an unholy hybrid of Beaches and The Exorcist that blends teen angst, adolescent drama, unspeakable horrors, and a mix of '80s pop songs into a pulse-pounding supernatural thriller.

The year is 1988. High school sophomores Abby and Gretchen have been best friends since fourth grade. But after an evening of skinny-dipping goes disastrously wrong, Gretchen begins to act…different. She's moody. She's irritable. And bizarre incidents keep happening whenever she's nearby. Abby's investigation leads her to some startling discoveries-and by the time their story reaches its terrifying conclusion, the fate of Abby and Gretchen will be determined by a single question: Is their friendship powerful enough to beat the devil?
