I'm looking for a beautifully written story about a vampire student and Lupin. She is the daughter of a dark vampire and good witch and is asked to help Lupin search for information (in Romania, I think) and not to follower her father's footsteps.

Things don't go off very well at the start as his wolf comes through when searching the castle for Black.

She ends up befriending Sirius (as he loved her mother) and he helps their relationship.

Her father, however, smells Lupin on her when she visits and things go bad to worse.

This story is brilliant and I can't find it on FF. It is completed, rated mature and there was a half finished sequel by the author about them nearly marrying but getting disrupted.

Any help would be much obliged and I will forever be in your debt! If it's on another website any links will be greatly appreciated. Xx
