Hi
What I remember of this story is that the MC is brought in to an Amish-like cult to become the leader because their men are leaving the cult in droves and it is disappearing.
The MC discovers that in their effort to make a women-friendly society, girls in the cult are treated like princesses and boys are treated as servants, girls have their own rooms and boys sleep all in a barn, girls can have sex with the elders and among them, boys must remain celibate, that kind of thing, so naturally most boys end despising their sisters or leaving the cult.
Can anyone help me to find it? TIA
