Jo March, now married to Professor Bhaer, works together with her husband at Plumfield School, a sort of foster home where the couple hosts the children in their care. Some of them are "difficult," but they find in Jo and the professor two teachers willing to the hard work of dosing, differently for each, commitments and goals. The integration of study and work, the belief that goodness is worth more than strength, and that if a boy makes a mistake the first person responsible is the educator, make this work truly unique: a defense of nonviolence and a clear recognition of children's rights.
