Vivian Ellenshaw is fat, but she knows she doesn’t need to lose weight, so she’s none too happy to find herself forced into a weight-loss camp’s van with her ex-best friend, Allie, a meathead jock who can barely drive, and the camp owner’s snobby son. And when they arrive at Camp Featherlite at the start of the worst blizzard in the history of Flagstaff, Arizona, it’s clear that something isn’t right.
Vee barely has a chance to meet the other members of her pod, all who seem as unhappy to be at Featherlite as she does, when a camper goes missing down by the lake. Then she spots something horrifying outside in the snow. Something…that isn’t human. Plus, the camp’s supposed “miracle cure” for obesity just seems fishy, and Vee and her fellow campers know they don’t need to be cured. Of anything.
