Eleven-year-old Willow doesn't want to go to her dad's weird old summer camp any more than she wants her family to move to the weird old town where that camp is located. But her family—and fate itself—seem to have plans of their own. Soon, Willow finds herself neck-deep in a confounding mystery involving stolen snacks, suspected vampires, and missing campers, all shrouded in the sinister fog that hides a generation of secrets at Camp...whatever it's called.

When twelve-year-old Willow went to her weird new town's even weirder summer camp, she didn't expect to get caught up in an ancient mystery involving forest-dwelling vampires, living garden gnomes, and other completely bonkers creatures most people would never believe exist. Now she's not only involved, she's marked—too close to the heart of an ages-old quest for power and control than she should be, and too concerned about her new friends and the dangers they face to let them go it alone. With the help of a spell book and her scrappy crew of camp friends, Willow is about to step through a doorway to magic and discovery that will change her world forever.

After former camp leader Clarence P'sketty Tooter is freed from a hypnosis spell, he remembers everything, including that pesky pre-teen Willow and her scrappy friends. But most importantly, he remembers the ancient mystery surrounding Nowhere's sleep-away camp. Now, Tooter seeks revenge against Willow and her friends, and inadvertently awakens a long-dormant evil which seeks to destroy the world in the epic conclusion to the Secrets of Camp Whatever trilogy.
