Maul

Most of the men are gone, those that are left compete to be the top 'Pig' and women who can afford it or who get it as a perk of the job vote on which one's offspring they want to have. Dr. Baldino already has a clone daughter but she wants the real deal and her work developing assassin bugs on a male 'Y-autistic' clone is supposed to get her there.

That's one thread of the novel, the other is girlz w/guns shooting up the maul.

Some mysteries are there to be seen throughout, you just have to twig, and others are slowly revealed over the course of the book. From about 40% (I'm a Kindle reader) it became unputdownable for me and I'll definitely be reading Tricia Sullivan's Lightborn soon.
