Harry Potter!

I have been reading a lot lately and I love it, but it has become kind of an addiction. Marc told me, jokingly of course, that he wouldn't marry me unless I read Harry Potter. I didn't want to read them, but I had the time. I finished the first two before we were married, then I read the third one about 6 months later. Marc kept telling me I needed to read the 4th one, but I kept putting it off because it was so big, I read it in a week, I am working on the 5th one now and I have to force myself to stop, at this rate, I will be done with the series in the next 3 weeks, now I need something new. I might reread the Twilight series, it has been awhile since I read them as they came out, but I have a list of a few others. Any suggestions?
