It's really great to continue reading the story of Jo and Professor Bhaer in this book. Even though it focuses on the boys they teach and take care of, it's easy to see their characters shine through. The boys (and girls) get in a lot of trouble, but ultimately try and fix their mistakes and learn to be moral people. One thing that the afterword noted which I found interesting is that there is no villain in this book, even though it is a children's book (the writer compared it to Harry Potter, LOTR and others where there is a prominent villain). Alcott shows that the evil is inside of people when they choose to act on it, rather than on good. Jo and Professor Bhaer teach this to the children and try to show them that acting good is always better in the end. It's a good moral book for children, teenagers, and adults alike.
