Adventure is brewing at Scarytales, a creepy old house where storybook villains like the Big Bad Wolf, Captain Hook, and the mean stepsisters from "Cinderella" come to life. So when Nancy, Bess, George, Katie Zaleski, and her parrot, Lester, go to their friend Amara's Scarytales sleepover party, they're sure to have a great time. But the fun really turns scary when strange things start to happen and Lester disappears from his cage. Even the villains of Scarytales are spooked! Could the troublemaker be Amara's pesky little cousin Ernest, or the grouchy troll with a plan up his sleeve, or the wicked witch who threatens to pop Lester into her bubbling brew? Can Nancy solve this creepy case before Amara's birthday is ruined?
