I found my pre-writing and all I could find was the theme of it. My theme was "Buck had to be able to endure harsh beatings and learn from his mistakes. If you were weak, you'd have no chance of surviving in the harshness of nature. Learning to adapt to a new environment is important as well. The people and dogs who couldn't adapt ended up dead. The story revolves around surviving." My thesis was "Buck learns how to survive by using his natural and newfound skills making his strength and adaptability the main theme in Call of the Wild."
