You state that it’s Harriet Potter in this story but you keep using ‘him’ and ‘he’. You might want to take a bit more care with that. It’s just confusing.

Please make this a hilarious parody of all those silly & fluffy Dramione fics! I could really do with a big laugh after an exhausting year.
Bet she'll get really cross when they start calling her Mione with an American accent!

it's feel pike you write your own diary lols.
still, if harry is a girl, why blush? is she prefer women?

Yeeees! I hope to see more!

Nice plot twist at the end there. The information was given really calmly, so I felt more pleasantly surprised than shocked, but still. Expectation subversion! I like how it was all diary entries too and that you could see her slowly turning from “Lyra Malfoy who suddenly has memories of another person” to “person who reincarnated into Lyra Malfoy”. Very interesting. Transporting into a HP Fanfic rather than the canon is a very creative decision and, from what I’ve interpreted of the summary, I’m guessing that there will be other AU-things that Lyra will realize are not canon? I wonder how she’ll use her future knowledge, given that it might not always be correct?

A piece of advice I will give to you would be to tag characters on your story. It will help people find it better if they’re just browsing while also giving them an idea of what your fic will revolve around.

I look forward to seeing how you continue!
