That's the very real question facing college freshman Jenna Blake, and it has nothing to do with romance and heartbreak. A second grisly murder mystery is unfolding at Somerset University, and her job as a pathology assistant at the local hospital brings Jenna too close to the haunting crimes. Everyone has a theory on the nature of the killings, including Jenna's older half-brother, Pierce Logan, who's new in town and has some odd ideas about why someone would want to steal a human heart. Meanwhile, Jenna begins working on her own heart when she meets a fascinating older man. But there's little time for dating when the Thief of Hearts declares Somerset the perfect hunting ground - and someone very close to Jenna is the prey.
