What is a good thesis statement for the adventures of Huckleberry Finn?

A thematic I thought of for the book was, "During the journey to find ourselves, friendship and reality are the things that remind why we are on the journey in the first place." When Huck is deciding whether to turn in Jim back to slavery, he remembers the adventures and hardships they faced together. Remembering their intimate friendship reminds Huck why he decided to help Jim escape slavery in the first place.
