Great suggestion, yardgnome! "Brokeback Mountain" is a wonderful story - not a novel, though, but a short story/novella in Annie Proulx's story collection Close Range: Wyoming Stories. I managed to find a volume which only features "Brokeback Mountain"; not sure how easy they are to come by, though. Since I own the "Brokeback Mountain" volume but not the entire collection of stories, I've only read "Brokeback Mountain" but would love to read the whole book. If we were to read it, should we read the entire collection since the stories all deal with similar themes and geographical landscapes?
I still vote for The Year of Magical Thinking for our first pick, but I'm definitely open to the possibility of reading and discussing Annie Proulx. She's a marvellous writer.
