Inspired by the author's own experience of losing his friend to suicide, this is an insider's look at someone who kills himself for desperately selfish reasons, and what that does to those he leaves behind. Jeremy wakes to find himself still alive - not in a hospital room, but in the bedroom he does not know, to find a year has passed since the day he should have died. Locked in limbo, a Groundhog Day of living death, unable to remember an entire year of life, Jeremy slowly pieces together the forgotten days, finding he was, on the whole, a pretty unpleasant person to be around.
Definitely one for the angst-monkeys, I'm sure a lot of people will find this pretty heart-wrenching and love it accordingly. I liked it well enough, but never loved it. It's very obvious that you're reading a translation: the language isn't quite right, which gives it a slight edge of unbelievably. It gets preachy and moralising at times; the author is clearly religious and this frequently breaks through into the prose. All in all, it's an interesting experiment, nicely executed, that didn't quite work for me, but simply by dint of personal taste.
