This is a re-write of Double Trouble. Harry finds out that Dumbledore has been meddling a lot more then he thought; he has a twin sister. He's also found out that the prophecy was a fake; but there is another one, one that Dumbledore doesn't want him getting his hands on. This story includes Meddling!Dumbles, RonMione!Bashing, Slash, and creature!Harry. Enjoy!

SLASH. Serenity always thought she was a normal girl, with normal foster parents...Until the faithful night after they moved into their new house. Now she finds out that she's the twin sister of the boywholived!...Bad summary! Sorry.
