[Get Off the Unicorn is a delightful collection] of science fiction short stories…. McCaffrey—a master storyteller—makes the collection even more enticing by adding an introductory anecdote for each tale. While the book as a whole shines with warmth and humor and makes fine entertainment, several stories are exceptional. "Changeling," dealing with homosexual parenting, and "A Proper Santa Claus," describing a small boy's concept of the "right kind" of Santa, are moving human studies whose quality is far and above the usual fare.
