Prom House is a YA horror/thriller. I bought my copy new.
Review:
Kylie and her friends have rented a gorgeous beach house so they can party as much and as loudly as they'd like after prom. Unfortunately, not long after they start their partying, Kylie and her friend Aubrey discover Cam, Aubrey's boyfriend, dead. Kylie is convinced that he was murdered and that his murderer could still be somewhere nearby. When the cops arrive, however, Cam's body is gone, and Kylie and the others can't convince them that it isn't a prank.
Now the cops are gone, and everybody's stuck in the house as a violent storm hits and takes down a nearby power line. When yet another person in their group winds up dead, it seems more and more likely that whoever killed Cam is still among them. Can they find the killer before whoever it is claims more victims?
