What are some good books for 17-19 year old female teens?

I used to love reading, but don't ever seem to find books that interest me as much anymore, otherwise I don't have the time to look. It seems that when I was younger, it was easier to find books- Nancy Drew, Junie B Jones, and a million other books. I have found some good books still, but I was wondering if anyone could provide me with a good list of books for teen girls from 17 to 19 years old? I often like teen romance. I am also a Harry Potter and Twilight fan, I like witches and vampires sometimes but don't think I'd ever read about aliens, and I probably wouldn't like a book that is centered around paranormal things. Take twilight for example, it is all about vampires, but it revolves even more around teen relationships and problems so I like it. I have liked books by Catherine Clark (Better Latte Than Never), Rachel Hawthorne (Thrill Ride), and Marianne Curley (Old Magic) also. Any help would be appreciated=) Thanks!
