This was an outstanding story. Earth is fighting Romeo through multiple alternative realities after surviving a
kind of event.
The planet is divided into non-incorporated people, settlements and cities. The cities are the core of the defense, the settlements feed the cities and the others range the world in an unstructured, random tribal manner.
Black provided a large cast but spent sufficient time crafting each so that you got a good feel from their behavior, feelings and actions. The aliens inadvertently introduced the Earth to a magic like power fueled by fontani people who provide the power to build the marvels of the city and defenses.
Black successfully blends the nomadic gypsy like folks with the settlement people and the often arrogant city people. Black shows how cooperation, particularly from diverse elements can succeed where fighting alone would fail.
This was a totally captivating book and it seems to set up a sequel, I can’t wait to read it.
I highly recommend.
