Nightfall (The Vampire Diaries 5)

Elena Gilbert is back from the dead, but she’s come back changed—with newfound powers and blood that is irresistible to vampires, including Stefan and Damon Salvatore, the two vampire brothers who love her. Unfortunately, it’s not just vampires who are drawn to her. Darkness is infiltrating her hometown of Fell’s Church and is taking over the minds of young girls. Even worse, a demon has taken possession of Damon, causing him to turn on his brother, Elena’s friends, and even on Elena herself.
