What makes a person go to a freshly dug grave and dig up a discarded baby with no means of keeping that child hidden or even alive?

For five years, this child has had no interaction with humans but one. Then, this child then survives in the wilderness alone and makes his way into civilization.

He has no mother, no father, no relatives, and no history. Yet he has a desire to break through all the assumptions made about him to become a man of integrity, to be understood and accepted. Just when he is finally making his way and becoming a benefit to others and an asset to society, he is wrongly accused. He is convicted without being allowed to make any kind of defense.

Possum is slow to trust people but quick to trust almost any horse. His encounters with people produce anxiety. They make assumptions about him that cause frustration, irritation, and annoyance. He is chased from his childhood home and compelled to live alone in the wilderness.

Even when he finds friendship and a place to grow and learn, he is pursued by men who want to capture him or kill him. He survives and flourishes and begins to make a real life for himself before he is falsely accused and has to find a new way of living.

How can he maintain his integrity, be true to his new values, and yet stay out of a prison that he does not deserve?
