My children and I enjoyed reading this lovely book. It is a simple story but it shows a good friendship between two sisters, and how they deal with a third child who joins their playing. It's also a story that allows a parent to bring up the issue of bullying without it becoming a heavy subject. My kids both loved the way Carly outsmarted Lily Jean.
My 5 year-old remarked that the book teaches that others won't want to play with us if we're rude, and that if a friend does not want to play the game we've chosen, we could make up another one. It's an age-appropriate tale with attractive watercolor illustrations suitable for this age group.
