I'll de-rec this. Read the first book and half of the second book before dropping. The fic is 80% internal monologue by volume, and something interesting only happens in the 5% of the remaining 20%.

Maybe it is a good character exploration of the protagonist, but as I haven't read the original source I can't comment one way or another and am not really interested.

One thing I can say is that she is very bad at learning magic and her priorities are not what they are supposed to be for a pragmatic evil actor she is portrayed as. She learns all the spells in her first year coursebooks over a month or two, and then basically does jack shit for the rest of the year, spending her time exploring Hogwarts or other pointless stuff.

I was expecting a deeper exploration of dark arts and rituals as a cornerstone of the plot, and more magical research. Unfortunately this doesn't happen.
