I read this as an eBook from Kindle Unlimited. Available as an ebook, paperback and hardback.
In our time, a nuclear holocaust of unspecified cause has laid waste to civilization. In a last ditch effort to save everything, the US Government secrets enough people in suspended animation and technology away in underground silos to rebuild America. Through a fluke, One silo, in the Pacific Northwest, doesn't wake up at the appropriate time and sleeps on. Then a cave in occurs triggering a wake up of a handful of people who only have a few supplies some weapons, and and food. The other 'sleepers' die in the accident, and the remaining technology is lost without heavy recovery equipment..
At the same time the survivors outside the silo carry on and build new lives for themselves and their future generations. The Pacific Northwest has turned into three cultures, one of horse bourne nomadic tribal people, small feudal kingdoms, and a smaller grouping of seaborn tribal folk. Some of these tribal people are subject of the various kingdoms and some manage to stay independent through careful political maneuvering, which sometimes affects the politics of the tribes themselves. They seem to have become racially homogenized.
The Dog People are a tribe of warrior nomads with a fierce reputation, but with a leader who is trying to keep his people independent and at peace with the rest of the world. His son, who was born with a prophecy of greatness attached, is struggling, however. Tribal politics serve to isolate the younger man from the tribe, and make him something of an outcast in his tribe.
At the beginning of the story, a priestess of 'Church', a sort of altered Christianity, and the only legally recognized religion in the Pacific Northwest arrives at the Dog People's encampment to serve as a healer, but with a secret agenda of her own.
That's the set up, I won't tell you any more, but it triggers a first rate story unlike other similarly set up post apocalyptic story arcs I've read. (and I've read a lot of them)
The writing is quite good, and if there are any typos or spelling and grammar mistakes, they are so subtle, I didn't see them. There seems to be 9 books in this series from the 1990s (how did I miss this writer and this series?) However They now seem to be bound in 3 volumes of 3 books each. All of which seem to be available from within Kindle Unlimited.
I am re arranging my to be read list to accommodate reading the rest of the series. Highly recommended.
