I've just read "We Need to talk about Kevin" and it's soared to somewhere near the top of my list. I started to read it yesterday evening and couldn't put it down. Today it was pouring with rain, so I used that as an excuse for a spectacularly lazy day and I read the entire book. Very thought-provoking, brilliantly written. Although reviews talk about the shock at the end, there were a number of clues that led me to guess, but that didn't spoil it. Not a´light read, but well worth it.
