After Pia’s grandmother dies in a freak accident, the neighbors in her little German hometown of Bad Münstereifel glance at Pia with wary eyes. But then something else captures the community’s attention: the vanishing of Katharina Linden. Katharina was last seen at a parade, dressed as Snow White. Then, like a character in a Grimm’s fairy tale, she disappeared. Ten-year-old Pia and her only friend, the unpopular StinkStefan, suspect that Katharina has been spirited away by the supernatural. Their investigation is inspired by such local legends as that of Unshockable Hans, visited by witches in the form of cats, or of the knight whose son is doomed to hunt forever. Then another girl vanishes, and Pia is plunged into a new and unnerving place, one far away from fairy tales—and perilously close to adulthood.
