This was a lovely fic and I enjoyed how things just slowly worked to create the bonds between the couples, and Harry's gradual realization that he does actually like Snape and vice-versa.
I don't normally read Draco/Hermione, but I could actually believe it in this instance. I also thought that Ron was perfectly in character; I could see him desperately wanting to cling to old traditions and Hermione being too modern to want anything to do with them. Lucius felt very real too, and I could easily see him willing himself to die because the world isn't going to turn out to be what it wanted to be.
