The Boggart (A Puffin Book) - Softcover

Here (Susan Cooper) uses a peripheral part of that imagined world to create her mischievous main character, an Old Thing from the Wild Magic, and brings him into hilarious, tragic contact with our unimaginative civilization. ... As long as writers with Susan Cooper's skills continue to publish, magic is always available. (New York Times Book Review)

Accidentally transported from his remote Scottish castle to the bright, fast-moving, hi-tech city of Toronto, the highly mischievous Boggart simply can't resist the opportunity for pranks, and wreaks havoc for the Volnik family, inheritors of his distant castle home. But the Boggart doesn't mean any real harm, and when he begins to pine for the rolling Scottish mists and the sound of bagpipes, he turns to his two young friends, Emily and Jessup Volnik, for help.
