I've been a bit remiss in commenting, but I felt compelled to on this story mainly because I, like many other reviewers, almost didn't read the story based on the warnings (I mean, all those Harry/ and no Snape??? j/k) and am glad I did. I won't say I was overwhelmed by the amazingness on every level, I was slightly squicked out by the pendant, and the brutal sex was difficult to read, without much joy and happiness to balance it out (which is my personal preference), but I was extremely impressed by the totality of the AU and the way the change in universe was so completely embedded in the story; and I liked that you chose to kick the Dark Lord back old school. It was actually kind of creepy how much Grindelwald seemed like a more casually violent and prejudiced Dumbledore.
I would love to see a fluffy mpreg sequel to this, that would be way more up my alley, and I was really interested in the relationship Harrison and Severus would develop.
