Two girls playing together can do many things, according to Keiko Narahasi’s luminous watercolor illustrations and short, patterned narrative. “Two girls can fly a kite, or dig a hole, then make a tunnel and meet in the middle.” They can also “get really really mad,” but only for a little while, before they begin another adventure. Girls of several racial and ethnic heritages romp, jump, and caper in this cheerful celebration of preschool-age fun. (Ages 2-4)
