Wes is tired of being the quiet kid. Tired of the bullies. Tired of the Boone brothers making him feel invisible.
This Halloween, he's ready to change everything-with a costume that'll finally scare the Boone brothers back.
When he buys a strange pair of monster teeth in a dusty costume shop, Wes thinks he's found the perfect touch. But he has no idea what he's really signing up for. At first, it's fun. The teeth are creepy. The scares are real. And for once, people are noticing him. But the more he wears them, the more he changes-and not just on the outside. Now Wes isn't sure if he's still in control... or if something monstrous has taken his place. Can his friends save him before it's too late? Or will Halloween night change Wes forever?
