One of the most memorable and irresistible characters in all of literature—the Wizard Howl—is introduced in Diana Wynne Jones's classic fantasy novel Howl's Moving Castle and makes guest appearances in two stand-alone sequel novels, Castle in the Air and House of Many Ways. Howl's Moving Castle was adapted into an acclaimed and Academy Award-nominated film of the same name, produced by Studio Ghibli and directed by Hayao Miyazaki. Sophie Hatter never intended to set out and seek her fortune. The eldest of three sisters, Sophie thought she was destined to fail. That all changed the day the Witch of the Waste turned her into an old woman. In order to lift the spell, Sophie barges into Wizard Howl's moving castle and strikes a bargain with Calcifer, his fire demon. But Howl is outrunning a curse of his own, and soon Sophie realizes that nothing is as it appears. . . . Howl, Sophie, and Calcifer return in both Castle in the Air and The House of Many Ways, two stand-alone sequels full of mayhem, secrets, and magic.
