Colleen Madden grew up in a crazy Christmas house and, like Kerry, she found a break by spending time with her neighbor who was from another country. She has illustrated many children's books, including the bestselling What If Everybody? series, written by Ellen Javernick, and the picture-book adaptation of All I Want for Christmas Is You, by Mariah Carey. She recently published Monkey Walk, her debut as both author and illustrator, and is currently working on her first graphic novel. She lives in the Philadelphia area with her husband and two sons.
