Below are a bunch of my favorite books. Many of the authors have plenty of other books as well, so if you like one, you’ll probably like some of their others. They are categorized below, but many books could easily fit into multiple categories. I tried to limit myself to 5 in each category, but I’ve read more in each and could recommend more. I don’t really read fiction, so you can expect all non-fiction. The history stuff often reads in the style of fiction, if that’s your taste.
Readers
Readers are a good place to start because, they are essentially a, “best of” collection of multiple writings. They also make good refresher courses for people who already know some stuff.
