If you're at all like me, you have a stack (a growing stack) of books that you intend to read but haven't yet tackled. I'm especially bad about collecting nonfiction books that I really enjoy and will eventually get to (except for whatever is still in that stack when I die or go blind). Yes, I suppose I've shown my colors as non-Mustachian in regard to buying books.
I find that I kind of have to be in the right mood to start on some of these deeper books, so I tend to always be working on one of these while also reading something lighter (definitely fiction, probably scifi or fantasy). I can burn through the 'fun' books in a week or so while it might take me 2-3 months to get through one of those more educational tomes.
Anyway, here's what's in my book in box at the moment:
The Last Lion - The 3rd and final of Manchester's Winston Churchill biographies. The first 2 were fantastic, and he (Manchester) died before this one was published
If This is a Man - Primo Levi's account of the concentration camps
Truman - McCullough's bio
I'm currently casting about for a new 'fun' novel and am thinking something from Neal Stephenson might do the trick. Seveneves was fantastic, and Cryptonomicon is a classic. Sadly, my (local public) library doesn't appear to have any of his stuff at the moment. See, I'm trying to do better!
