In this rather blinkered tour through the annual cycle, a child tallies the exact dates of the solstices and equinoxes while observing natural changes that mark each season. Some of those observations are simplistic—in spring: “Every day the air gets warmer.” “June 21st is the first day of summer. Green sprouts spring up from the field.” The possibility that seasons might not be so distinct beyond the author’s New England home is acknowledged only in an inconspicuous, small-type note. In characteristically clear, uncluttered illustrations, Halsey places the young narrator/naturalist in a generic rural setting. Previous Rockwell/Halsey collaborations, such as One Bean (1998) and Two Blue Jays (2003), introduce narrower topics to young children more successfully; for a basic but more inclusive introduction to the seasons, there are plenty of other choices.
