Diary: A Novel
Chuck Palahniuk
   If you're a fan of anything Palahniuk has ever written (Fight Club, for example, or Lullaby or maybe Choke -- those are the ones I've read, and they're all good) then you must read this. And if you're going to read this, do it soon, before anyone tells you anything about it. Don't even read the back cover.

Trust me.
You may feel lost at first, but you're clever; you'll pick up the story as you go along -- and it'll be worth your while.
