This is the only fic I've come across so far where I wished there was a rating higher than 9. I loved the concept and it was so well written I couldn't tear my eyes from the screen. I loved how Snape would exile himself for the rest of their lives, how Harry and Draco make mistakes but suffer the consequences rather than running away, and that even after a lifetime it still had a happy ending. I actually ached at some parts and even as I read it, wished it wouldn't end. A really superb story.
