The first "book" in the Devious Amelia Salvatore series.

Amelia is the twin sister of Stefan Salvatore, and little sister to Damon. She had no intentions of visiting her home town again, but when Stefan contacts her, asking her to come back to Mystic Falls, she discovers that something big is going down in the supernatural world. Something to do with a certain Original Vampire she'd planned to avoid for the rest of her life.
