Nick and his family are forced to leave Earth in order for him to keep his cat, Horace — because all pets are now banned, as they use up badly-needed resources. They settle on Plowman's Planet, where they discover a variety of strange and wonderful alien life-forms. But not all of these weird lifeforms are benevolent — and the family is involved in a series of increasingly dangerous mishaps. Can Horace and Nick manage to outwit the Wub, the Werjes, the Trobes — and the most dangerous of all, the Glimmung? Philip K. Dick's only children's book, first published after his death, brings together many of his most famous alien creations in one gently humorous tale.
