What happens when a stuffed toy lemur who, apparently, can see, hear, and feel all the stirrings of being alive, meets a little girl who is excluded by her older sisters as the "baby" of the family?

This is the story of a friendship, a friendship nobody understands. After all Clemmy's simply a stuffed lemur, isn't she? It's only that Gwynnie senses there is more to Clemmy. To Gwynnie Clemmy is real. Is Gwynnie right? Is Clemmy truly real?

What will happen if the two are separated? Will they truly still be best friends forever?
