Rayne and Sunshine McDonald, 16, may be physically identical, but the similarities stop there. Rayne has been covertly studying to become a vampire, and her moment of love-at-first-bite has arrived. Unfortunately, her decidedly nonvampiric twin is at the receiving end of that kiss of death. Now Sunny has just one week to un-bloodmate herself from the newly appointed King of the Coven, Magnus, and return to human form before her dream date to the senior prom. Though filled with teen and supernatural romance clichés and slang, Mancusi's take on the vampire myth is entertaining. The language is a little coarse, but the characters are sound and behave like many teens with their references to underage drinking and sex. Liberal doses of humor keep things interesting. The plot gains momentum in the second half, and the surprise ending will leave readers bloodthirsty for the next installment of the twins' misadventures with the undead. A ghoulishly fun read for a summer day at the beach.
