I was looking to do something non-fiction because I had done a strip 'My Mom Was a Schizophrenic.' I really enjoyed the process of doing that strip despite its subject matter. To do it I'd had to do a lot of research and reading and I figured I'd like to do that again.
My parents were keen for me to have the education they themselves never had. They weren't able to guide me towards particular books but they encouraged me to read which I did randomly and compulsively.
