Great question, and one that I asked just before going to Mozambique for 10 weeks a few years back. I'd just bought a kindle, which were not available outside the USA back then, and asked a few interesting folks I was chatting to at Foo. Here are my resulting first few kindle purchases:
The Match King
Heros Die (I bought the rest of them)
The city and the city
Every patient tells a story
Blindsight
Born to Run
Hot, Flat & Crowded
The Autobiography of Ben Franklin
The Hunger Games (!)
And on it went - asking for recommendations was a fantastic thing to do. I'd asked for fiction as I was going there to work and would be too exhausted at first to do much else.
So I do encourage everyone to give some names of books. And yes - do take a good camera, do take binoculars - Leica if you can afford them, and embrace the experience.
A few years later I went to Antarctica on a boat for 30 days offline. By then I had hundreds of books on kindle, and several devices to read them. This is basically a solved problem now. I did take Wikipedia in offline state, which was useful.
In decades previous when traveling I cared about weight and price per word and focused on "good" books - books that you know you should read but which need a bit of effort. When you are off the grid and in countries where there are few English books then it was a great way to read great books.
But now the Internet is everywhere. It might be flaky, and it might be painful to access, but you'll be able to find access to buy and download books relatively easily.
Three recommendations, aside from the above which I enjoyed a lot.
Bill Aulet: Disciplined Entrepreneurship, covers the topic very well and generously references everything else.
The Circle by Dave Eggers paints a picture that's creepily familiar already.
League of Denial will have you shake your head gently and sadly at NFL and other contact sports.
