The Greatest Individual Warrior of All

This trilogy is the farthest thing from space Rome, or from any real human society, possible. Sexual dimorphism does not meaningfully exist. None of the men in this book would have any reason to be attracted to any of the women in this book. Female warriors are invariably flawless, driven solely by bloodlust and the desire to dominate and conquer. Their only faults are caring too much about winning and working too hard to kill their enemies. It's never really made clear what Darrow wants, except that he's super pissed his wife is dead, and hierarchy is always bad so he wants less of it.
