Recently started Through the Dark Continent (volume 1) by Henry M. Stanley. Yes, the "Dr. Livingstone I Presume?" Stanley (though he probably didn't actually say that).
It's purely factual account, and full of useful things like tables of figures to illustrate how we could economically exploit the Africans, but the details of the expedition planning and the expedition itself are interesting. And Stanley's prose is quite light and easy to read, not the heavy slog that some Victorians are (though maybe I've read so many Victorian writers that I've become accustomed to them).
The main annoyance of the edition I have is that a fold-out map that's claimed to be inside the back cover isn't there. And I love maps, so that's quite a big annoyance.
