'To the Heart of the Nile: Lady Florence Baker and the Exploration of Central Africa' by Pat Shipman.
It's an entertaining read, but highly fictionalized in its' presentation (lots of filler... invented dialogue...). The author admits to as much, in the introduction, as a way of fleshing out the subjects... but it's just a weird departure from the style I am accustomed to.
I read quite a bit of Orson Scott Card when I was younger - and not to politicize... but I recently came across the unflattering news that he expends a fair amount of effort in denying LGBT rights. Bummer.
