Clamburg used to be a popular tourist destination. But when Vendetta learned how to make “fiends” – “hideous things” that torment everyone in town – no one wanted to go to Clamburg anymore. No one except new girl in town Charlotte, whose ridiculously chipper, oblivious attitude immediately drives Vendetta crazy. Vendetta spends much of her time trying to turn Charlotte’s smile upside down, but try as she might, she can’t crush Charlotte’s endless optimism. What’s worse, Charlotte thinks they’re pals! It’s a battle royale of friends versus fiends.
