The Author has written a lovely children's story to help kids confront, in a roundabout and fun way, the issue of immediate gratification, which plagues many children (and their parents). This issue is related through the story of a boy, Bill, who has a "gimme want wants" attitude that is not serving him well. Though the analogy of a pig in a pen, Bill's grandpa teaches him that a pig is best left in its pen, just like the gimme gimme want attitude is best kept contained. This story is a great way of communicating an important lesson, and parents will surely like the values it is teaching. I also think the story concept section was well written - the author clearly put a lot of thought into the underlying concept of this book. The book interactive nature is also great, and kids will benefit from putting the lessons of this story into practice.
