The third book in the middle-grade series that's part Scooby-Doo, part A Series of Unfortunate Events, and entirely genius! Follow the Sinister-Winterbottoms on their most outrageous adventure yet, when they find themselves at a normal summer camp! After leaving the Sanguine Spa in pursuit of Edgaren't, the kids find themselves at a mysterious summer camp, Camp Creek. There are lake games and happy counselors, and there's even a tie-dye cabin. It's all very . . . normal . But if Theo and Alexander know one thing, it's that normal doesn't always mean good. When everyone around her starts acting strange, Theo wonders if maybe the fumes from the tie-dye cabin are seeping into their brains, and she resolves to investigate what's really going on at Camp Creek.    The third book in #1 New York Times bestselling author Kiersten White's Sinister Summer series continues the adventures of the Sinister-Winterbottoms and their aunt, who never saw a discount vacation destination she didn’t love.
