Worst book you've ever read

[TumorAttitude]

I hated that the Catcher in the Rye had basically no point other then Hey, I'm Holden Caulfield, relate to me. But it was really well-written and I didn't get exhasperated halfway through like I do with most "classic" novels.
For my birthday last year, my mom bought me the Twilight series. I read half of the first one and it was awful. Bella is seriously the blandest character in modern literature, you could not make a more blatant Mary Sue if you tried.
