High school is over, but Nora O'Malley's life isn't, which is weird now that her murderous stepdad Raymond is free. Determined to enjoy summer before her (possibly) imminent demise, Nora plans a ten day backpacking trip with Iris and Wes. Her plans hit a snag when Wes's girlfriend tags along. Amanda is nice, so it's not a huge issue—until she gets taken. Or rather, mistaken...for Nora. All because of a borrowed flannel. Now Raymond has a hostage. Nora has no leverage. Iris has a spear and Wes is building boobytraps. It'll take all of their skills to make it out of the forest alive. There are three problems: Someone is lying. Someone is keeping secrets. And someone has to die.
