This is the first paperback of a short novel Tolkien wrote for his children in the mid-1920s. It was first published in hardcover in 1998.
In 1925, Tolkien’s son Michael, then nearly five years old, lost his miniature toy dog on the beach. Tolkien wrote Roverandom to console his son. It tells the story of a dog named Rover, who annoys a wizard and is turned into a toy. The toy Rover is then lost on the beach by a young boy, and later found by a sand-sorcerer, who animates the toy. Roverandom tells of the random adventures of this toy dog Rover, on the far side of the Moon and under the sea.
Originally published by Harper Collins in 1998 and reprinted many times since then.
