twilight

so for the last 3 weeks or so I have been joining the crazed teen fans of Twilight. I watched the movie when it first came out and put off reading the books. 3 weeks ago my best friend challenged me to just read the first few pages and if I didnt like it, no harm, no foul....well needless to say I just finished the 3rd book out of 4 and my hands and mind are itching for the next one. I am trying to pace myself because I think I'll be sad when I am finished.
