Rosa, I've never seen Brokeback Mountain, either, but I would like to read the novella.
I too, liked Into Thin Air, but it's been a long time since reading it.

Right now I'm reading "The Salt Path," by Raynor Winn. I couldn't get through "Other Birds."

The Salt Path is about a Welsh couple who, upon losing their farm and the husband getting an ugly terminal diagnosis, decide to embark on a 600+ mile walk around the South West Coast of Britain.
