As soon as I hit, "There's no driveway," I knew I was going to positively adore this story. I am absolutely in love with your Hestia, and while I've never had much sympathy for Petunia as a character, the way she relates to Hestia made me love her too.
This story is just plain charming in the best of ways, drawing me in to read it one happy rush, full of wittiness and on-the-nose comparisons between the Muggle and wizarding worlds, and poignant in just the right spots. Reading this made my day, and I just know I'll be coming back to it in future whenever I want to read something smart, funny, and perfectly characterised.
