I will probably return to this book - in print - in a few months. I missed a lot of nuance from the audio book - probably was the wrong book for me to listen to in AUgust when I have my annual reading slump. Annie Proulx’s afterword was very interesting. She pointed out events I had glossed over in my listening - that I think would have been better understood had I been reading. 
At this point - I recommend the book - but not the audio version.
