I very much enjoyed the way you rewrote canon -- many familiar landmarks are still there, but with a twist. I particularly liked the way you allowed Harry a happier childhood, while still keeping the blood-protection strand. Also putting Bellatrix through the veil instead of Sirius was really neat, with the extra bonus that she then couldn't get Severus swearing any Unbreakable Vows! I found it touching that Severus was the only one to be surprised that he was the one Harry rescued from the lake in the Triwizard Tournament. The slow realisation of their feelings for each other was very well done, as was their love-making, and you gave them their happy ending. :)
