City Dog and Country Frog are as different as two creatures can be. However, throughout the span of a year, they share their games and friendship with each other. In the winter, City Dog sadly realizes that he can’t find Country Frog, but the following spring a surprising friendship emerges to offer renewed hope and joy. Relationships, seasons, transitions, and losses are the subtle subject matter of this book, winsomely illustrated by Jon J. Muth. Ages 3-6. (Hyperion)
