The kind of secret illustrated in the beginning (e.g. the ground has a secret; the picture shows mice crowded every which way in tunnels with an occasional snake trying to pass) is vastly different from the type depicted in the major portion of the book (e.g. fall has a secret; the secret is Halloween). The first ones are more effective; there is a notable humor in the discovery of those which is replaced by a guessing technique in the later ones. The carefully drawn, breezy illustrations, in which the artist has cleverly combined pencil and color, are directed to a young audience that will enjoy them. A near strong success by the author of It's A Holiday--Here's Why.
