Judy Blume is a renowned author, and her work has gone on to support generations of young readers. The author, who published a series of works that continues to influence middle grade literature, released her first book in 1969. The One in the Middle Is the Green Kangaroo did not initially draw much notice, but it received more attention after Blume published her third work: Are You There God? It's Me, Margaret. (1970). That novel, which tells the story of a young woman struggling with faith, has been frequently criticized for its mature elements, though it became an instant bestseller.
