My oldest brother's been locked up for a few years now. But a couple years ago we started reading books together, averaging about 5-7 a year depending on the length. I usually buy 2 books on amazon: one for me and the other I have sent to him, and we parse out sections to read each week or every other week depending on how busy I am. So when he calls me we discuss that week's reading in depth. It's pretty cool - I enjoy it a lot, especially since neither of us were into books when we were young. The last three we read were fiction titles and pretty long but all were great books - though vastly different in style and content.
11-22-63 - Stephen King
Infinite Jest - David Foster Wallace
Aztec - Garry Jennings
The first is your typical Stephen King. About a guy whose friend finds a worm hole into the past and recruits him stop the JFK assassination and hopefully change the future for the better. Good read, easy read. I recommend it if you haven't tackled a long novel before.
Infinite Jest was no joke, had to read it with my phone on hand so that I could follow along with a page-by-page wiki that listed out the obscure references and words. Weird and confusing at first, but when you move along through it, all the story-lines start to connect and make sense and it becomes a crazy ass roller coaster. Took about 3 months for me to finish. I would try to explain the plot, but it's hard to explain; look it up on Amazon if you're interested. Long difficult read, not for everyone.
Aztec was about a poor Aztec peasant named Mixtli who goes from being a commoner to being a Noble and decorated warrior. The book is about his rise in Aztec society and how it all changes when the Spanish come in. It's a good story that incorporates a lot of historical details if you're into that.
Up next is a book called Underworld by Don Delillo, another long one.
