It’s okay, I guess.  It’s a book about moving and saying good-bye.  To try to cheer themselves up, some friends who are facing one of them moving away decide to throw a good-pie party instead, for the whole neighborhood, and after the party they gaze at the moon, referring to it as a pie they will always be able to share.  There doesn’t seem to be any real climax that it builds to, or any surprise or humor or compelling reason to make the reader care.  A little on the bland side.
