I remember reading it earlier this year, i think it just dropped at the time.

Basic premise was that men and women are separated out, women control society and men are considered lesser and are forced underground to work in factories. The MC is a dude that seems to be pretty okay with his monotonous life in the factory, they feed him drugs to keep him peppy and energetic. One day, as he's about to get beat, a women steps in and tells him his freedom has been purchased and he's to be a servant to a pair of rich daughters up on ther surface.

That is about all I can remember.
