Pairing: Damon/Elena, Damon/OFC
Fic Title: Darling, I Want To Destroy You
Rating/Warning(s): R (for adult themes)
Why This Must Be Read: If you can't hear Ian Somerhalder actually saying the words in your head, I'll eat my hat. No lie, it's just the perfect Damon voice of all time, and the storyline is wonderful. You meet a new character you've never seen before, and she's delightful. And, wait for it, there is pay off at the end that is a little ambiguous, but just perfect for the story. Go. Read. NOW.
(ETA: Mods there is no Elena/Damon tag as yet.)
