I was happy to see this story posted today because it meant that I had time to read it. I really wanted to see how the story came together.
I loved Aberforth. I liked his lingering dislike of Albus, especially, but also the way that he allowed Severus to live his life, even if he disagreed with his choices (e.g. having strange men up to his room).
Kieran/Severus was delightful, maintaining a lot of his character while embracing his new life. You made Harry into a man who makes his own decisions, and for that alone I would have liked this story. He figures out what he needs to do for himself, without pleasing the others around him.
