How lucky we Team Cauldron folks are to have, of necessity, stolen you away from Team Snitch! Seriously, whichever "team" you technically belong to, this is an amazing contribution to Team Snarry.
The truth is that I was predisposed to enjoy the story just based on length alone, but this is really quite an achievement. The mystery is wonderfully constructed - or at least I had no idea what the truth was (I just assumed this was something of an AU). However, when the mystery was solved, all the little differences made perfect sense, even down to Harry's inexplicable talent with potions preparation.
As for the characterizations...I cannot tell you how much I hated Snape for a while there. I gave him time to recover from his illness, to cope with what I assumed to be amnesia, and then...I couldn't stand him and had no idea what Harry was doing with him (which...is canonically perfect, truthfully *g*). But then when Harry finally put his foot down and said "no more?" I cried and wanted them together. :)
Anyway...this is really great and well worth the million hour investment I made in it.
(BTW, I'll be adding it to my recs page at the next update.)
