Suzanne Lang is the author of the New York Times bestselling Grumpy Monkey books as well as several other titles. When she’s not writing books, Suzanne writes for animation. When she’s not doing that, she hangs out with her very funny kids, feeds her many pets, and tries (but usually fails) to take a nap!

Max Lang has illustrated over 20 books including all of the books in the Grumpy Monkey series. When he is not making books he makes films. He has co-directed several animated films including The Snail and the Whale, Zog, Room on the Broom, and The Gruffalo. He has received a BAFTA, two Emmys, two Oscar nominations, and many other honors for his film work. In his spare time he tries to make his kids laugh with dad jokes, and when he inevitably fails, he takes his dogs for a walk.
