The first book in the notorious Sweet Valley High vampire trilogy, this was a fun read but didn't quite match the delirious highs of the SVH werewolf books I read recently. Published 9 years before 'Twilight', it reads a lot like 'Twilight', with a brooding, dark haired young man who is romantic one minute and standoffish the next moving into a small town and making the local girls swoon. One of the swooners is SVH twin Jessica, and naturally her sister Elizabeth is suspicious of newcomer Jonathan Cain, not least because a dead body with holes in its neck turns up in town just after he arrives. 
All a lot of fun and builds to a pretty great cliffhanger climax.
