so as an h/d shipper, i haven't been keeping up with the games, as i am dreadfully behind on the worldcup as it is. but when i saw your story posted, i had to read it.
this was absolutely gorgeous. so much canon was hashed out in the most intense and satisfying way. the relationship between snape and harry developed so perfectly, and was so honest. minerva was delightfully written, and albus and lily were wonderfully three dimensional. the touching palms against the portrait nearly killed me, especially when snape and lily took up the tradition. so did harry's taking down the portrait to curl up against it. so many incredible, heart wrenching details.
the entire premise was truly original and felt entirely possible and probable in the hp universe--particularly having a wizard's debt with oneself. and i loved the parts about who would meet you when you died. the ending was just right, and i loved that harry was back to being a blushing 40 year old.
