Bryan Chick is the author of the Secret Zoo series. He originally had the idea for the series when he was a nine-year-old and wondered what would happen if zoo exhibits had secret doors that allowed children to go inside . . . and the animals to come outside. Bryan Chick lives with his wife and three children in Clarkston, Michigan.
