With her stick-on fangs and widow's peak drawn in waterproof eyeliner, Sylvie is an expert at pretending to be a vampire. More kids at school would know that if they bothered to join her monster LARPing (live action role playing) club. Not even her dad understands her passion for the undead and denies her request to attend a monster LARPing summer camp. But Sylvie is not so easily deterred.

She decides to tell her dad she's attending another camp located near Monster Camp then sneak over to her real destination after he drops her off. Sylvie feels bad lying to him, but there's no way she's going to miss the chance to finally meet other kids that share her interests. And when she lays eyes on Monster Camp, she knows it was all worth it--the immersive campgrounds look like they came off a Hollywood lot!

But when an obnoxious kid dressed like a werewolf gets punished by being magically turned into a Pomeranian, Sylvie realizes she made a critical miscalculation. These aren't LARPers, they're real monsters, and Sylvie's preferred costume means she's placed with blood-sucking, human-biting campers who would breathe fire if they knew the truth about her. She has no choice but to try to stick it out by doing exactly what she does best: pretending to be a monster.
