The Final Conflict...The Last Deadly Kiss
Now she rises from the dead to recreate the powerful vampire trio.
Summoned by Elena, he keeps a promise to her and fights the most terrifying evil he's ever faced.
Joining the brother he once called enemy, Damon battles this new horror with strength, cunning, and deadly charm.
The fourth book begins six months after Elena's death. This book is told primarily from Bonnie's point of view. At a surprise birthday party for Meredith Sulez from Bonnie McCullough, Caroline Forbes, Sue Carson and Vickie Bennett, they contact Elena using a Ouija board after Bonnie admits that Elena contacted her in a dream. Elena warns them there is evil in town with them, and that they are all in danger. She tells them they need to summon someone but gets interrupted, presumably by an evil spirit, before telling the girls to run. Before all of the girls can get out of the house, Sue is thrown from the second floor balcony and dies. Vickie goes insane after the ordeal. With Matt's help, Bonnie and Meredith perform a spell to summon Stefan, who arrives back in town with Damon. Tyler Smallwood is revealed to be a werewolf in league with this dark force and Stefan faces it alone after failing to save Vickie. And after a battle with the evil, Elena comes back. An angel, as it seems, whose blood is irresistible to all vampires.
