Steph, I haven't read any of Bobby Anne Mason's short stories, but have enjoyed some of her novels, In Country and Feather Crowns, the latter about quintuplets born to a pioneer family. Just looked up Mason on Wiki --In addition to being a journalist, she has a PhD in literature -- dissertaton on a work by Nabokov.
I have to return Olive Kitteridge to the library, but it should be easy to pick up again, seeing as how it's mainly short stories. Nlhome, I can see what you mean about not liking her, but I haven't read enough yet to make a decision. I've been reading while travelling and sleeze (Dubus' Garden of Last Days) won out over bitchy.
