my recent obsession

So I was in Wal-Mart one day and I happened by the book section out of boredom. I came across a book that looked interesting and I knew I had heard the title before. It is called Twilight. Well I realized it was a series and remembered a good friend of mine had told me she was reading it. So I figured what the heck give the first one a shot and if I like it maybe I'll buy the rest. So I bought it and went home. I am not the hugest reader so I wasn't in that big of a hurry to start reading it. But then I finally had some time and I dug into it and let me tell you I could not put it down! I got about halfway through the book and immediately ran out searching two different stores for the other three because I didn't want to have to wait in between books. So it takes me less than a week to read all four of these books because I made time for them. This series has brought me back into the world of reading. I became so obsessed that I really could not stop reading them. I hated running errands because it meant less time for my obsession. I mean of coures I'm a mother so I can't sit around and read all day but I was staying up late and I mean extremely late every night just to read these books. Now that I have read them all I feel sad and lonely without my books to keep me company. So I'm searching for a new series to entertain me and praying I find the same obsessive nature in some other series. At the same time I'm highly doubting that will happen. If anyone has any recommendations I am open to suggestions. Especially vampire books I am so obsessed at this point that I would love a good vampire series.
