Because of my awesome Nook, I have discovered the author Amanda Hocking. She writes paranormal romances. If you liked the Twilight books, you will like these too. I read her first series, the Trylle Trilogy, and fell in love with her writing style. I'm currently reading the 4th book in her My Blood Approves series. This series is about vampires.
If you have a Nook, these books are all under $3 from Barnes & Noble. And some are lendable so let me know if you'd like to borrow them. :)
