Giant, technologically superior aliens have conquered Earth, but humankind survives - even flourishes in a way.Men and women live, like mice, in burrows in the massive walls of the huge homes of the aliens, and scurry about under their feet, stealing from them.A complex social and religious order has evolved, with women preserving knowledge and working as healers, and men serving as warriors and thieves. For the aliens, men and women are just a nuisance, nothing more than vermin.Which, ironically, may just be humankind's strength and point the way forward.
