I liked this story very much, particularly the way you wove canon characters together in such a different setting. You've managed to capture their personalities and characteristics amazingly well here, and at the same time, you've worked some of their canon histories in, too. Seeing them all appear here, written in such a clever and interesting way, made for compulsive reading. I really wanted to know what was going to happen to them, whether they'd survive or not. You made me care about them. Sirius's fate was inevitable, but done extremely well.
Your Snape is conflicted throughout, but at last manages to find happiness with Harry, and with his faith intact. The way you tie the end of the story up by repeating the beginning works very well for me. I love how Harry and Snape seem so settled and in tune with each other, and these sentences resonated for me:
This is not a life I would have chosen for myself, I realise. And yet. I find myself curiously content.
Perhaps I might even be happy.
I've stayed up way past my bedtime to finish this; I couldn't stop reading, which shows the strength of your story telling. I even managed to survive all the religious references, which is something I'd not normally choose to read. But if they meant so much to Snape, it was the least I could do. ;-)
What a strong and powerfully written story to finish the Games! Go you!
