I’d second the opinion about all Proulx fiction being worth reading, although Barkskins went a bit shit at the death sadly. Her short stories are gems. I’d recommend Tim Gautreaux if you enjoy Proulx and Cormac McCarthy too. Difficult to go wrong with either.
tbh all the Proulx are good, I'd just read all of them!
I'm getting through this at the moment:
Its great. beautifully written.
