Summer Days and Nights by Wong Herbert Yee (2012)
On a hot summer day, a little girl finds ways to entertain herself and stay cool. She catches a butterfly, sips lemonade, jumps in a pool, and goes on a picnic. At night, she sees an owl in a tree and a frog in a pond, and hears leaves rustling. Before long, she's fast asleep, dreaming about more summer days and summer nights.
