A picture book look at the summer solstice in the Northern Hemisphere features brief descriptions of how peoples as varied as the Ancient Greeks, the Chumash Indians of California, the builders of Stonehenge, and others marked the longest day of the year in the past, as well as ways in which the solstice is observed in some places today. A simple explanation of the cycle of the seasons and typical, child-centered summer activities are also part of this easy nonfiction narrative illustrated with colorful, clean-lined illustrations showing summer and solstice activities.
