Let me begin by stating that this is the first novel that I have read in at least five years. (I recently also read and reviewed Bunker's "Pennsylvania", but read "The Last Pilgrims" first).
This book is interesting, as it portrays the world after a total economic/political/and societal collapse. The world is governed my monarchies, and is somewhat medieval. A group of pacifist plain people are living in Texas, besieged by the troops of the (obviously Roman Catholic) king of Aztlan, while being protected by the Ghost Militia (a group put together by a right wing patriot guy before the collapse).
I enjoyed the story, though I am not in full alignment with the characters ideologically. The main part of this difference is that Bunker portrays a world whose geographical kingdoms are divided by religious affiliation more than by race. As an ethno-nationalist, this makes me a bit uncomfortable. While no racial intermarriage is depicted, there is an obviously ethnic Mexican "spy" from Aztlan who rides with the militia to defend the peaceful plain folk, and several militiamen and plain folk who's name or physical description indicates them to eb Hispanic (though the majority of militia and plain folk are clearly white). Eventually the duke of Louisiana side with Aztlan becasue of his allegiance to new Rome -despite obvious ethnic differences, and makes war on his (white) ethnic brothers in Texas.
Despite my racial discomfort, I did enjoy the book.
