Told through poetic letters, this inventive collaboration from Newbery Honor winner Joyce Sidman and two-time Caldecott Honor–winning artist Melissa Sweet reveals the everyday conversations between “big” and “little” objects in our ecosystem. Delightful!

Dear Sky,

Hello! It's me, Bubble!

I'm here!

Someone’s breathed me

awake!

What is it like to be little? What is it like to be big?

Award-winning poet Joyce Sidman explores both in this lyrical picture book. Whether it’s a small bubble writing to the enormous sky, or a mighty oak reassuring its tiny acorn, these surprising and delightful poems examine how we’re all connected—in both big and small ways. Brilliantly illustrated by Caldecott Honor–winning artist Melissa Sweet, Dear Acorn (Love, Oak) will have readers dreaming up messages of their own to this big, beautiful world.
