That was an utterly fantastic fic! The sex was perfect, Severus had his snark, and drawl. The desperation of the Malfoys was awesome! Harry doing his best to help everyone involved. Severus becoming a parselmouth was an unexpected surprise but such a good one! I found your wonderful fic through a rec from one of my flisters on Lj!
I did notice a couple of discrepencies when Harry and Severus arrive back from Australia to Narcissa and Draco in Grimmauld. When the rooms are being described throughout all of that it's not consistant. I saw it described as the study, the drawing room and the sitting room. With no indication that they had changed rooms.
There was also the odd spelling mistake but that is bound to happen with such a long fic.
