Michelle Medlock Adams began her writing career at a young age as the editor of her elementary school newspaper! As an adult, she became a successful journalist, but when she had two children of her own, she quickly turned to writing children's books. Michelle's many titles include the bestselling What Is . . . holiday series for WorthyKids/Ideals. Michelle divides her time between writing, speaking at conferences, and blogging. She has two grown daughters and lives with her husband, Jeff, in Bedford, Indiana. Aside from illustrating, Lizzie Walkley loves decorating her 1940's house and exploring the countryside just outside her door. Walkley studied illustration at Plymouth University and has since worked as an illustrator, with credits including God Made the Sun and God Made the Moon. Walkley lives in England.
