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 twenty books, including all the titles in the Grumpy Monkey series. When he's not making books, he makes films. He has co-directed several animated movies, including The Snail and the Whale , Zog , Room on the Broom , and The Gruffalo. He has received three BAFTAs, two Emmys, two Oscar nominations, and many other honors for his film work. In his spare time, he tries to make his kids laugh at dad jokes, and when he inevitably fails, he takes his dogs for a walk.
