Late last week I read a couple of the "Conversations with the Bookless" series at BSC Review. One of the authors (I forget which one, sorry) mentioned that a favorite short story of his was "Until Gwen" by Dennis Lehane. Since I enjoyed A Drink Before the War and was looking for a timewaster, I set about to track down this story. It appeared in The Atlantic a couple years ago and also in a couple fiction anthologies.
Luckily, one if the anthologies is available for preview over at Google Books and the entire story is included in the preview. Do yourself a favor and go read the story. It's a good one.
Then head over and read an interview The Atlantic did with Lehane. It's very insightful and extremely engaging.
