[Guest Helena Dante]

I remember this story about Sirius being bitten and made a vampire. He can control the shadows and the order sort of turns against He the. Becomes obsessed with Harry and wants to mate with him. Eventually he does get with and change Harry into a vampire. At the very end the monster who changed Sirius is a very old vampire/demon who changes Draco malfoy and Sirius, Harry, and hermione stop him outside hogwarts. This was originally placed on fanfiction but might have been removed because it is mature. If anyone can tell me what its called and where it went. I would appreciate it.
