Love and Necromancy

Draco Malfoy has a problem. His father has died, but decided to come back as a ghost. Since the manor's magic still recognizes him as master of the Manor, Lucius refuses to allow Draco to access his inheritance without a wife. Feeling as though he is trapped in the same home he grew up in with no options of escape, he calls up the one witch that he believes can help him; Hermione Granger.
Hermione has been spending her time helping Magical Creatures and the next entity she wants to assist are... Ghosts. She is on the brink of a breakthrough that could allow wizards who chose to stay on Earth as ghosts the option to move on.
But would she help him? The same boy who was a Death Eater? The bully from school who made her life miserable?
Hermione has decided that he has changed since his time at Hogwarts, so agrees to help him. What could possibly go wrong from them working closely together for weeks at a time?
