Valentine becomes even more of a threat when he befriends her brother, Billy. Raven must try to shield Billy, even as the biggest excitement of the year approaches: attending prom with her immortal love, Alexander. And while Alexander is one kind of vampire--sweet--Raven soon learns Valentine is another. Could Valentine somehow know Raven´s private thoughts about turning into a vampire?
