Read Wilbur Smith for historical action set in Africa, usually with a strong dose of Empire. But don’t expect anything filling, or you’ll be disappointed. The man has written 30 “Epic African Adventures” according to his website. I’ve read several in the past, but hard to remember which, given the titles and subject matter. The Triumph of the Sun was an airport pickup. First two-thirds lived up to my expectations, but the last third dwindled.
Stick with the Courtney novels if you want to start somewhere with Smith.
