That was so amazing - a story I think I could come back to again and again. I haven't read many stories that look a bit at things from Petunia's perspective, but I love the ones that get it right and this one really does. But what I think is so noteworthy here is just how layered this story is - you manage to tell so many intricate stories and so deftly - you give us a full-blooded Snarry with wonderful, complicated details (Snape's cruel trick of teaching Petunia to introduce herself as a Squib, and then later Petunia's wholesale belief in Luna's ideas, which comes so perilously close to the trick that it's a uniquely tense thing, despite the beauty of their friendship). I particularly loved both how you told the story of running away from the Hogwarts letters from the Dursley's perspective, AND how that still didn't change the fact that she had kept her love from Harry in the end. Almost every section of this could be spun in its own direction - Just amazing, amazing work. Bravo.
