girls in their late teens/early 20s live in a worn house together
Some girls create a pact or some kind of a cultish group. Any girl that accept the rules can live in this house. The rules are No contact with men and maybe something more that I don't remember.
I think many of the main characters have had an experience with aggressive sexual behaviour from men, one girl had an uncle, which constantly tried to f*** her.
The leader in the house was a different girl though. I think the leader became a radical leftie and went to join some south American/south-east Asian revolution later.
