When a family goes for a stroll one morning and encounters an adorable little creature with no collar or tag (who just happens to be sitting in the wreckage of a UFO), they happily adopt the lovable stray. They name him Grub and set about training him, but that doesn't work out so well. Maybe he isn't really a stray, after all—but how on earth will they be able to find his family when he seems to come from somewhere out of this world? Complementing her wry text for readers up to 7, Molly Ruttan's charcoal and pastel illustrations supply much of the unspoken humor of this tale.
