This is an unusual and intriguingly different Snarry to the ones I'm used to reading, and I enjoyed it a lot. I had to think quite hard to keep track of everything, but it was so interesting that it wasn't a chore.
I'm not keen on cross-dressing!whore!Severus, so it's a measure of your clever plot and good writing that I couldn't stop reading.
I loved the little phoenixes and dragons on the bottles; and the way Harry kept changing back and forth between himself and Arthur was a good touch.
I loved the ending ... that was realistic and satisfying as well.
