Adam Lehrhaupt has traveled to six continents, performed on Broadway, and lived on a communal farm.

He received the E.B. White Read-Aloud Honor for his debut picture book, Warning: Do Not Open This Book, illustrated by Matthew Forsythe, and is the author of over a dozen published and forthcoming picture books including the six-book Chicken in . . . series, starting with Chicken in Space, illustrated by Sahar Kober, and I Will Not Eat You, illustrated by Scott Magoon. 

Deb Pilutti wrote and illustrated Ten Rules of Being a Superhero, Bear and Squirrel Are Friends, and The Secrets of Ninja School, and illustrated Idea Jar by Adam Lehrhaupt.

Her inspiration for this book began with a doodle of a rock with a face. It looked like it could be a character, but Deb dismissed it, thinking, Rocks don't DO anything.

They just sit there. That would be a boring book. Luckily, she dug a little deeper and Old Rock's story came to life. Deb lives with her husband and their border collie, Wilson, in Ann Arbor, Michigan.
