The Lost Libraries of Timbuktu

I have to say, outside of ancient Egyptian history I never studied, read, had lectures concerning anything involving the history of Africa. However, the more I see concerning the continent's history (for instance- Egyptians mummy bodies having cocaine and tobacco in their bodies, the traverse of Northern African Kings to Mecca, or the potential start of the Egyptian religion in the Northern Sahara desert.) the more interesting the history becomes.
