When the days stretch out like a slow yawn, and the cheerful faces of Johnny-jump-ups jump up . . . then it’s time to get ready for summer! From flip-flops and hide-and-seek to fireworks and ice-cream trucks, from lemonade stands and late bedtimes to swimming in the lake and toasting marshmallows, there’s something for everyone in this bright and buoyant celebration of the sunny season. Tom Brenner’s lovely, lyrical ode to summers spent outdoors will strike a chord with anyone who’s ever counted down the days until school gets out, and Jaime Kim’s jubilant, nostalgia-soaked illustrations leave little doubt that summer is indeed a time unlike any other.
