While I’m not in the target audience for this, I skimmed through the first chapter and this seems really cool - great job! I will definitely keep this one in mind if it ever becomes more relevant to me.

One small comment: the /about page only has the books listed and nothing else. Some people will probably be interested in knowing a thing or two about the author before getting the books (and there are probably a million people with the same name, so difficult to Google)
