All 4 books!!!
On December 28th, I bought and began reading Twilight.
On Monday, February 23rd, I finished Breaking Dawn, the 4th & final book in the series.
On Saturday, March 21st, the day Twilight comes out on DVD, I'm hosting a girls only movie night. :-)
I feel relieved and sad that I finished them, the story coming to an end is not fun :-(
I'm hoping she'll revisit it and write a follow up in a few years.
