This book took me a long time to finish because it felt a little dull. It does pick up the pace and get more interesting, but it soon ends, so you can only enjoy the increased pace for a little while.
This book is the story of a couple traveling in Africa after the war (presumably WWI). They have a male friend who is also traveling through the Sahara with them. It is interesting because it's a foreign land and a different time. The couple has a strange dynamic in their relationship, and the other man adds to its strangeness. It has a rather abrupt end that is somewhat ambiguous.
This book has discussion of sexual situations, but they are brief and are not descriptive. It is just matter of fact statements that it happened. The sexual behavior of the main characters doesn't fit social norms and is inappropriate in my view.
I wouldn't say this book is worth the time it takes to read.
