August's book is King Solomon's Mines, by H Rider Haggard. The library has a few copies (14, plus large print etc). Here's the Goodreads summary (https://www.goodreads.com/book/show/23814.King_Solomon_s_Mines?from_search=true). It is rollicking good yarn, but very politically incorrect.
The general theme is: a book set in Africa. Others that spring to mind are Out Of Africa by Karen Blixen, The No 1 Ladies Detective Agency by Alexander McCall Smith, Long Walk to Freedom by Nelson Mandela, the When The Lion Feeds series by Wilbur Smith.
