It's Rowdy Dawes's last year at Harcourt Autumn, a month-long sleepaway camp in Oregon for fledgling vampires. Unable to be trusted on their own, Rowdy and her fellow campers are supposed to take the month to strengthen bonds between clans, practice their various gifts, and better manage their often uncontrollable thirst.
But Rowdy's final Harcourt Autumn will not be a bittersweet hurrah. After the death of her best friend, Leena, Rowdy's only goal is to bring her abuser to justice. The only problem? The person responsible for Leena's taking her own life is the camp director.
In the months leading up to camp, Rowdy's collected every scrap of evidence she can find, from a worn copy of Leena's suicide note to all the texts and photographs she sent documenting the abuse, in the hopes of confronting the director. But when a human girl is found drained of all her blood in the lake wearing one of Rowdy's shirts, she quickly discovers this Harcourt Autumn is not something she could ever have prepared herself for.
