Anna's new friend, Emma, is everything Anna wants to be: fearless, fashionable, and always up for doing something fun. The girls even look alike, and soon they're fixing their hair the same way and sharing clothes. But Emma is also kind of a troublemaker. She likes to sneak off school grounds at lunch, and she doesn't seem to like Anna having any other friends. When Emma's sense of adventure takes a sinister turn, Anna starts to worry: Is her mirror-image BFF really a dangerous evil twin? Written by both established authors and fresh new voices, "Poison Apple" books are perfect for girls who love thrilling ghost stories, spectacular supernatural tales, and spooky mysteries!
