This inventive debut combines the pleasures of a thriller, a school story, and a real estate listing in its witty and insightful exploration of what it means to be--and lose--a friend.

Sam and Asha. Asha and Sam. A perfect pair of friends whose differences complement well, and whose main similarity, autism, means they understand each other. They are a fixture, an established thing, just as Donnybrooke, the mansion that sits on the highest hill in Coreville, is the acknowledged best house in town--and Asha's dream home. But when Sam is accepted into elite Castleton Academy, leaving Asha to navigate public middle school alone, she begins to wonder if the things she is certain about are so fixed after all. Because soon Sam is spending time with Prestyn, Asha's tormentor whose family also happens to own Donnybrooke, and who have forbidden Asha from setting foot inside. Told from the points of view of Asha, Sam, and Donnybrooke itself, this remarkable debut explores themes of prejudice and classism as it delves into the mysteries of what makes a person a friend and a house a home.
