I'm currently reading Catch-22. Really recomend it to you if you have the time (It's not that long, only 450-odd pages). Not what I would call an easy read, as the book is pretty much one paradox after another (which I would hope you would pick up on, because the title of the book literally became synonymous with paradox after it was published) but it's really not all the difficult for me to get through as long as I'm not distracted/interupted mid chapter. Don't really want to give too much away, but I'm on chapter 26 and it's really good.
After I'm done with it, I'm going to read The Fountain Head, All Quiet on the Western Front, and then One Flew Over the Cuckoos Nest. When I'm finished, I'm open to some serious suggestions on what to read next if you have any recomendations. Thinking of some Hemingway or Updike's Rabbit books, but anything you want to recomend will probably go higher on my list. :D
