I love all of Mo Willems' books. This particular one is very entertaining for young children because they respond to the pigeon all throughout the book. It reminds me of a young child questioning his parents over and over and each time they say "No." Only this time the child is the adult and the pigeon is the one asking over and over again. The illustrations are wonderful, funny and entertaining and they draw lots of comments from the kids. These are great for pre-school, reluctant readers in first and second grade, and once in a while, you will find an older child reading it. Or me.
