Inhalt: The last time Iris's and Violet's families went on a trip together, the girls turned their rental home into an epic haunted house—and Iris has brought all her spookiest supplies to the cottage they're calling home for the next week, ready to re-create the magic they'd shared. But in the years since, Vee (don't call her Violet) has become closed off and short-tempered and wants nothing to do with anyone, especially not her mom's new boyfriend. Vee's bad mood feels inescapable in the cottage. And soon strange things are happening that make it seem like the house itself is angry, too—doors are slamming, rooms that were perfectly neat a second ago are suddenly a disaster, and Iris hears pacing footsteps long after everyone's gone to sleep. Iris and Vee soon discover that the cottage has a secret history and that there's no need to stage a haunted house after all . . . because they're already in one.
