Secrets of Camp Whatever: Vol. 1 — Chris Grine

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.
