The mysterious Stalkers show up at almost the same instant 12-year-old Aiden Cain's grandmother dies. Following his grandmother's instructions, Aiden decides to seek out a powerful sorcerer at Melstone House. Yet when he arrives, he discovers the man died a year earlier. Melstone House now belongs to the sorcerer's adult grandson Andrew, who agrees to help Aiden with the Stalker problem. But then other problems come up: a creepy neighbor is stealing power from the land, and magic is leaking between the realms. Dealing with these issues would be so much easier-if only Andrew could remember anything his grandfather taught him about magic. Fantasy legend Diana Wynne Jones, who has captivated young listeners for generations, delivers a compelling and humorous adventure. Steven Crossley's narration captures the excitement and wonder as newly acquainted characters work together to prevent terrible consequences.
