I can strongly recommend 'The Masked Rider' ( https://en.wikipedia.org/wiki/The_Masked_Rider:_Cycling_in_West_Africa ), which is a fanstastic travellog of touring Cameroon on a bicycle.
Another great read is 'The Timbuktu School for Nomads' ( https://www.amazon.com/Timbuktu-School-Nomads-Across-Sahara-ebook/dp/B01HZFB8TE ) which chronicles the time spent living amongst the nomadic tribes of Saharan Africa, post 2001.
Also 'Facing the Congo' ( https://www.amazon.com/Facing-Congo-Jeffrey-Tayler/dp/1886913447 ) is pretty good.
