Hello, Elle,
Quite!
I felt troubled reading about incest, too.
I am perfectly happy to be ignorant of these things.
Maybe you should abandon the book?
I felt the same about "Caribbean".
The Caribs went in for cannibalism and I could do without that.
In "Mexico", too much human sacrificing going on.
But, Michener is telling it the way it was.
It is not Walt Disney tales.
I think something like "Poland" or "Iberia" would appeal to you, perhaps, or "Caravans".
I have not read "The Source", which is about the Holy Land.
It is a great day here, but frost not lifting.
And Miss O has just invited me for lunch on Tuesday!
Isn't it a wonderful world!
