Africa is also the center of the Arab world (Cairo + 2/3 of the arab world population is there) although the popular belief is that the middle east is.
What are you looking exactly for? I'm from the north so I can answer some questions about that part.
Sorry for being so vague, I don't have any starting point, except the books others recommended. I'll start digging and see where it gets me!
If you like the beaches, they offer lots of options (for Egypt go to Sharm ElSheikh. I have yet to do a better scuba diving).
Also I don't read books about countries. I visit them. People and especially authors are biased and also perceptions are very relative. A shitty country for someone is a home for another one.
For life, the 3 countries can offer good value quality/price. I live in Tunis. It has good food, good weather, nice beaches, new constructions that are cheap and easy to rent, etc... You can even get optic fibre for $25/month.
They have various issues especially with governmental services and transportation (particularly Cairo and Tunis). Tunis and Casa are definitively more open to tourists and foreigners than Cairo. Woman might find it unbearable to live in Cairo and Tunis would be the friendliest for woman in the whole of the Arab world.
One problem is that you can't travel around by car. If you are in Tunis, you can't jump to Algeria (very hostile to foreigners). You also don't want to jump to Libya. So you are limited to a 10 million population.
If you are in Egypt, beside Cairo and some touristic resorts, there is not much to go. It's downhill from the capital. The living standards are way too low.
If you're looking for a somewhat bleak overview of corruption and despots since independence, then try Martin Meredith The State of Africa: A History of the Continent Since Independence
One of my favourites is Blood River: A Journey to Africa's Broken Heart
Disgrace, by JM Coetzee. Outstanding book, emotionally difficult to read. Made into a not-too-bad movie with John Malkovich, but the book is infinitely better.
Granted, it's old and describes a version of Africa that there's not much left of, but I'd highly recommend it anyway.
Van Reybrouck describes the history of Congo starting pre-colonial, the colonization by Belgium and the entire aftermath. The books gives you a good understanding on the impact and the how of colonization and the history of Congo.
i) Ryszard Kapuściński, both the The Emperor and the Soccer War ( half of this is about Africa, other half is South/Central America)
ii) Chinua Achebe - Things Fall Apart - fiction but feels 'truthy'
This year I decided to read at least one book a month the ones I found most inspiring were: * Factfulness - how we can misinterpret the data and how most of us have a wrong idea about the state of the world * Let my people go surfing - growing a business organically, doing the last harm and taking care of your people. This book inspired me to start my own business and follow some of the ideas presented in this book. * When breath becomes air - memories of a neurosurgeon battling cancer. Very insightful and important read about dying. In a way it's a heavy book, I cried multiple times when reading it.
