I don't know what to say, but I can't not say something about this fic. It was hugely descriptive, but not in an overdone way, I thought. I felt as though you wanted us to actually see the places, almost to feel the roses and their thorns and to actually experience the story at an almost visceral level. Ron <--- that gutted me. Gutted. I liked the complexity of the Arithmantic equations and the concept of rationalizing love and hate, and of course, enjoyed how over the moon Hermione would get over working it all out. Severus was bitter and damaged and scornful and angry and all the things that a good Potions Master should be, and I liked that Harry didn't pussy-foot around him either. The descriptions of Harry's ghosts were very well done, I thought, and I particularly liked that he couldn't stand to be touched because that's such an essential part of human relations, and to have even that taken away from him by the curse/ghosts... *shivers*
When Severus cast those spells, mid-coitus, I knew he'd done something huge, and damn, if you didn't just rip out my heart with it. I managed not to cry, but only juuuuuuust. Long fic, but worth it. SO worth it!
