La malvada bruja del lago (The Wicked Witch of the Waterfront) (Campamento de Terror (Camp Creepy Lake)) (Spanish Edition)

Raven, the wicked witch of the waterfront, locks campers who don't pass their swim test into a rickety old shed on the beach. When the boys of Bunk Five all end up in the dark, locked shed, they count on their friend Nelly to help get them out.
