Query: Relentless despair

I don't know if I have ever read a book that painted a bleaker portrait of the human condition. Basically an anthology of relentless depair and cynicism but curiously entertaining. A book like this can't help but make you feel better about your own life because these characters are some sick sick puppies. The literary equivalent of a terrible train wreck. It is hard to watch but harder to look away.
