This is glorious. It has all the slow build-up of Snape in Azkaban, left by both sides, only to be retrieved as a member of the Order. I love the difference of Harry's leadership opposed to Dumbledore's pragmatism. I love everyone, including Hogwarts, damaged and hurting. The matter-of-fact way of Severus and Harry getting together, almost incidentally, and Snape's revival of Hogwarts is fabulous. I particularly love Hogwarts as a sentient being, and Snape unwilling to abandon her.
