There is a series out there called " House of Night". It is a vampire series like Twilight. My daughter has read all 5 books out there, and is waiting on the sixth. If you Google "House of Night" it should lead you to a website with the book titles and the author.
If you like more "grown-up" books, you could try J.D. Robb "In Death" series, or anything by Nora Roberts, Debbie McComber, Jude Deveraux, or Catherine Coulter
