Is it a meatball? A basketball? A pearl? As the round hole through the pages of this book grows larger, readers will come closer and closer to guessing the identity of the object that's round like a ball, hot and cold, every color, always moving, and home to us all. With a simple text and glorious collage artwork, Lisa Campbell Ernst offers a gentle tribute to our planet anda timely reminder that we all need to take care of it.
