Doug Cenko is an illustrator living in Chicago, IL. He has worked at an animation studio, a live special effects company and design agencies, but illustration is what he truly loves to do. When he's not drawing, you can find him... or better yet, not find him... mastering the art of hide-and-seek with his wife and daughter. Dr. John S. Hutton is a pediatrician and author from Highland Village, TX. His research and advocacy work is focused on limiting screen time for children and encouraging real-world play, reading and imagination. As a child, he loved to stare at the sky and play in the mud on his favorite planet, Earth.
