Twilight

Okok I know and yes I have been converted,but not completely. I still find parts of this series incredibly boring. I've skipped a lot of parts.
But these books are still really awesome :)

Twilight, New Moon, Eclipse, Breaking Dawn.

I saw the film the day it came out and it was fantasmic but the music at some points was aaaall wrong but the baseball scene was PERFECT! Muse - Supermassive Black Hole. Absolute. Genius.
But they didn't play Paramore once!! That was a let down...

Still, if you haven't read the book: read them.
If you haven't seen the film: see it (Jacob is so cute)

But yeah this overtakes Harry Potter no problem, even if Rob Pattinson isn't nearly gorgeous enough to play Edward :/ But you get used to it!

Just give it a try,its awesome.
