A story with good grammar, obeying "show, don't tell," no bashing and entertaining to boot. This is precious and rare. Thank you for sharing it.

Still, if the author wishes to improve there's two things I could mention. One would be that after 137k words we haven't reached 2nd year yet. The story is being buried in minutiae.

Number two would be the constant tension. Hardly any levity and release of tension makes it difficult to read. I'm not talking about how dark the story is. Struggle and tension are mandatory, but perpetual tension is exhausting. Even Quidditch stopped being fun for Iris.

However this criticism is like saying that 95% is awesome and 5% questionable and should not be taken to heart. In the end, just have my thanks.

Omfg Dumbledore is babbling about how blood magic is bad and does it himself, bloody hypocrite.
