Your father picks you up from prison in a stolen Dodge Neon, with an 8-ball of coke in the glove compartment and a hooker named Mandy in the back seat.
Sold! It's a great story and told uniquely in second-person (how often is that done?).
Stephen also links to an interview that Lehane did with The Atlantic. Here, Lehane talks about his books, his writing process and his thinking behind writing the story. Here's a brief quote:
At the time, I'd been teaching a lot and trying to get my students to understand that a character is defined most adroitly by his actions. I eventually decided to practice what I preached, and "Until Gwen" became a story in which the main character reveals himself entirely by what he does, as opposed to by what he thinks or says.
"Until Gwen" has just made it onto my list of favorite short stories.
