All the King's Men is my favorite book of all time. I did read it for my 11th grade english class and I don't know if I would have gotten as much out of it if I hadn't.
It's a great book about the depression-era southern politics and told from the point of view of Jack Burden who works for the govenor Willie Stark.
"Man is conceived in sin and born in corruption and he passeth from the stink of the didie to the stench of the shroud. There is always something."
That quote sums up the book for me. It's in the first chapter and everyone in my class had to memorize and recite it. If you haven't picked this up, I highly recommend it.
