Oh, I loved this story. When I saw it was you two, I knew it was going to be long, plotty, and sexy. I wasn't disappointed. I loved Lucius having to come to Harry to ask for help with Draco. I never would have thought of using Narcissa as the foil, but I think that makes sense. Her devotion to her son is ensconced in canon, so her craziness regarding Draco was perfectly in character.
As much as I enjoyed the Malfoys, I liked Harry and Severus more. I loved the blood bond between them, and the way they fell into a relationship. The sex was amazingly hot. Such a wonderful story--I wish I could vote. Fabulous job!
