I really enjoyed reading this book - the tone and concepts were just beautiful. It's a post-apocalyptic scenario infused with magical realism. After a plague spread (accidentally?) by peace-activist Buddhists, only a few survivors live amongst ruins. San Francisco has become a haven of artists, but a military cult based in Sacramento is set on forcefully establishing a new American empire. Pacifism faces down a philosophy of violent force... but primarily, this is the story of the orphaned Danny-boy and the wild girl Jax... and of the city itself, suffused with dreams and nightmares.
My only criticism is that while it's beautiful and poetic, the book paints both sides of the conflict with a broad brush, and avoids engaging some of the obvious questions (is there absolutely no crime or major conflict amongst the happy artists of San Francisco?).
Still, even though it may have limitations, it's still a lovely book.
