What a lovely, gentle story. I really loved how Harry initially learned lessons from books, but then Severus pointed out to him that simply reading a book doesn't change one's life. And personally, I found it incredibly satisfying that Harry found his family amongst non-magical people, too - I think you were really true to Harry's canon craving for 'normalcy', but in a way that didn't diminish him or substitute magical 'normalcy' for Harry's cultural reality.
