I read Regiment of Women a few years ago and that book is A LOT. It's so well-written (I love that dark academia vibe) and I think if the book focused on how Clare, specifically, is a cruel and manipulative if superficially charming person, then it would actually hold up pretty well. But instead it builds an entire argument that ALL relationships between women are like this if they get too emotionally involved. (IIRC there's a sequence where Alwynne gets lost in a terrifying dark wood, which is possibly a metaphor for lesbianism, given that she's rescued by the endgame love interest? And then possibly they have a talk about how Girls' Schools Are Unnatural and Coed Schools Are Better?) Even the title drives home the message.

Also POOR LOUISE. Alwynne at least gets away (possibly out of the frying pan into the fire, but at least she's still alive and kicking), whereas Louise... God, I just wanted nice things for Louise.
