This book is a bit of an oddity, interesting rather than good
It focuses on Gahzee, an American Indian who must leave his Enclave, which is free from the pollution that has wrecked the rest of North America (and the world) to recover some of the Enclave's high technology that has found its way out and into the wasteland.
The outside world is your typical post-apocalyptic wasteland, with Japanese Corporations taking over what is left. And this is where the first of the books problems come in. The Japanese characters are very stereotypical Yakuza, obsessed by personal honour and revenge.
The American Indians too are stereotypical, more 'spiritual' than other people, and not a little bit smug with it.
Finally, for some reason in the book the American Indian Enclaves had a higher technology than the rest of the world. I did wonder if it came from an outside source, but apparently not. It wasn't expalained and just seemed to be there to demonstate that 'native' ways were superior to Western ones.
That said, it was well written, and despite its faults, I'm glad I gave it a try. I just wish he had ironed out some of the faults, and it could have been an excellent book. Still, other people might get more out of this than me.
