Nick Hornby - A Long Way Down
Four vastly different people plan to commit suicide by jumping off a building on New Years, but they end up talking each other/themselves out of it for the time being. The characters are all pretty interesting, and the story never really goes where you expect it to go. Really enjoyable.
Go Ask Alice - Anonymous
A 15 year old girl's diary about the first time she takes drugs and her subsequent addiction. It gets quite dark in places, and she's very eloquent for a 15 yr old which kind of threw me a bit. One of my major gripes is that she just isn't very likeable. A good enough read.
