It deals with the adventures of a young dog, Rover. In the story, an irritable wizard turns Rover into a toy, and Rover goes to the moon and under the sea in order to find the wizard again to turn him back into a normal-sized dog. The author wrote Roverandom for his son Michael Tolkien to amuse him upon the loss of his favorite toy ¡ª a little lead dog. The work is in tone a children's story, but contains many allusions and references in the manner of "Farmer Giles of Ham".
