L.J. Smith & Aubrey Clark

Elena Gilbert is dying. When Damon avenged Stefan’s death, he broke his sacred deal with the Guardians — and put Elena’s life at risk. Instead of letting her die, the Guardians offer Elena one last chance: go back to the very beginning, to her senior year of high school when she first met Stefan and Damon, and prove that their love doesn’t have to end in endless death and destruction. But the Damon of the past is unpredictable and dangerous — and the only way to save everyone might be to give up the Salvatores forever. The final book in The Vampire Diaries series.
