Not canon compliant. Takes place between Deathly Hallows and Half Blood Prince. Harry helps Luna celebrate her birthday.
My version of what happened between the end of DH and the epilogue. Harry/Luna, Harry/Ginny, Ron/Hermione, Luna/Rolf.
The Trio, Neville, Ginny & Luna in the Unknowable Room of the Room of Requirements searching for the Ravenclaw Horcrux. Harry is paired with Luna and together they come across an object from Harry's past. Takes place after HBP. Not DH compliant.
Harry is having a very rainy day, a conversation with Luna Lovegood changes all that. Not really a romance fic, but could suggest future relationship. Story takes place the summer after HBP and suggest the use of a love potion.
Luna's little things are Luna and her daddy's big secret. Just a short little bit of Luna drabble.
