A gifted photographer completes his cycle of the seasons with a fourth group of lyrically captioned color photos. From March's first kite flying near trees still unleafed to a first beach trip and a wedding, Maass once again captures the season with unexpected insights into such expected sights as a mother duck and her brood, spring cleanup tasks, showers, flowers, holidays, and baseball. A fine conclusion to an excellent series. (Nonfiction/Picture book. 3-8)
