Yousef discovers a mysterious library in his neighborhood. There he meets Mrs. Pauline, the former librarian... who has become a ghost! But she's not going to go "boo!" in the hallways or scare visitors. Instead, she wants to live in the story of her favorite novel. To do this, she needs her lost magic medallion. Yousef, who dreams of adventure, throws himself without hesitation into this treasure hunt.
