Writing a thesis statement: the Count of Monte Cristo by Alexandre Dumas

Hello,
I understand what a thesis statement is but i do not understand how to create one. I am reading the book the Count of Monte Cristo by Alexandre Dumas. I don't necessarily want the easy way out or the answer just some ideas or some thing to think about when trying to think of one.

Thanks for the help!

The thesis statement is like the "good point" you make when you join a conversation. Your friends are talking about the story, and you say, "This story shows something about human nature. It shows that humans are willing to sacrifice a lot of time to seek revenge." Your friends would say, "That is an interesting point!"

When you discuss this book, what interesting observation do YOU make?

YOUR unique personality + the story = the meaningful thesis statement.

Put that thesis statement at the end of the first paragraph, and make sure every topic sentence supports it! :-)
