I'd really just like to quote dracofiend's comment as I think it matches perfectly how I felt about this fic. But I will attempt to make some of my own comments. ;)
Azkaban-what a totally incredible and yet sad place for Snape to be. And having to keep giving Harry depressants! Lovely sex scene-awesome how Harry 'recovers' saying "Fuck me anyway". *g* I loved the journey to find Harry in the Forest of Dean-what a brilliant recollection to weave throughout the story. Bill's role was great-even in just a few lines, he gained dimension for me. But from when Harry goes back to find Snape gone all the way through to the end-just wonderful, so suspenseful. I probably will read this again and see what I missed. Great job.
