If you like military stuff, read some of the earlier Tom Clancy novels. Red Storm Rising is about WWIII happening in the 80s. The rest of the Tom Clancy books (pre-2013) are really good. But that's if you're into that genre of books.
World War Z is one of my favorites. I like that it treats it as a real world thing and a realistic view on a zombie uprising. Fun read.
I really like political books and have been reading a ton of gardening books recently. I've expanded my garden a lot so I'm trying to make sure I don't screw it all up.
