Books for East Africa – Kenya and Tanzania

I'm looking for some books to read for an upcoming trip to Kenya and Tanzania.

I do prefer non-fiction, but would happily read fiction if it gives insight into the countries and people.

I'm interested in:

• Human history and evolution – would be good to learn more about human evolution in this is area (e.g. Olduvai Gorge)
• Nature
• Adventure
• Modern history, society and sociology – Swahili history, colonial history etc.
• Politics

A book that puts you in a place, and tells you a bit about the culture, society, history of the country. Might be a hard ask! Would love some recommendations that don't necessarily touch all bases, but are engaging and touch on certain aspects.

Some books I'm considering reading:

• Unbowed – Wangari Mathai
• In the Shadow of Man – Jane Goodall
• The Tree Where Man Was Born – Peter Matthiessen
• A Primate's Memoir: A Neuroscientist's Unconventional Life Among the Baboons Paperback – Robert M Sapolsky
• Into Africa: The Epic Adventures of Stanley & Livingstone – Martin Dugard

My favourite book is 'The Orchid Thief,' if that helps. It's a book that takes a topic (orchids and the orchid industry) and interweaves history, culture, narrative, human interest to tell an engaging story. I love some Hemingway books.

Another book I've had recommended to me in this general vein (but haven't read yet) is 'Cod: A Biography of the Fish that Changed the World' by Mark Kurlansky.

Thanks!
