"Writing seems to be as natural to Joan Aiken as breathing; her imagination is as untrammeled as ever, the precise construction of the astonishing plot lends conviction, and her style is as witty and sparkling with images." —The Horn Book

"Through interactions between characters, Aiken brings out the bittersweet ironies of friendships both otherworldly and in the here-and-now. Her sense of timing unfurls the mystery at just the right pace, giving the curse its rightful aura of power." —Booklist
