Great story. I hated that Severus was forced to rape Harry (and generally don't like non-con), but you made it work. It was so angsty, but there was hope at the end. Maybe Harry will be able to heal and return to Severus.
I must say that your characterization of Lucius Malfoy fits more into my impressions of him than Book Seven's bs. He seemed like a ruthless power-grabber who would eagerly step into the vacuum left behind by Voldemort's death.
