“A rose is a rose / And everything grows / When summer is summer is summer.” Inspired by a quote from Gertrude Stein (“A rose is a rose is a rose”), Phillis and David Gershator offer a catalog of summer sights, sounds, and activities in a lyrical picture book featuring trees and bees, holes and moles, logs and frogs, clouds and crowds, and much more summer fun. Some children won’t be able to resist coming up with their own summery observations. A pool is a pool is a pool perhaps? Cool is cool is cool? Sophie Blackall’s inviting illustrations picture a quartet (no, not a trio) of children, two white and two black. (Ages 3–6)
