This easy to read nonfiction book about Mo Willems will inform young readers about his career highlights.  There is no information about his childhood, which was a bit disappointing.  But the information about his career was interesting, easy to follow, and mentions his popular books.  Real photographs in the book enrich the format.  This book would make a great addition to a library, but am not recommending it because it doesn’t include more personal information about him as a child, student, or family member.
