Two of my choices were already on my TBR; the third fits my reading goals for next year and is available as an audiobook at OverDrive.
I've only been able to listen for the last few months and I'm still constrained. That said, I have to admit I own all 57+ hours of
Third Reich. Start Nov. 1, listen three hours a day and squeak in under the wire for the discussion.
My take on the other choices: I've got holds on
Sapiens at a couple of libraries, but I won't get it in time and it's pricey. I've read and enjoyed
White City, but don't want to re-read. I wouldn't mind reading
William The Conqueror; it's short, cheap and I'd learn something, but I suspect the book isn't very good.
Soul of a People goes on my "sometime, not now" list, but I'll bump it up if chosen.
That's it for me. A good slate.
