I did like this story for the most part. I was a bit annoyed at how all the pieces of shit seemed to get away with thier crimes, robbing harry, the abuse and obliviation of muggleborns, etc. But then I just hate to see injustice.
The only real complaint was you switched back and forth between robertson, and robinson for their last name, often from one paragraph to the next. I can understand not liking beta readers who voice opinions on content or plot, but a proof reader would still be helpful I think. Just to check for spelling, grammar or name consistency.
