Half a generation ago, a gesture in the name of peace turned out to spread plague and disaster. In San Francisco, the survivors are heir to a city transformed. It is a haunted, dreaming place peopled with memories, and in a strange way nearly alive itself. And although it is only beginning to recover from near-ultimate disaster, the city is at risk again. An army of power-hungry men are descending on San Francisco. Teenagers Jax and Danny-boy must lead the fight for freedom using the only weapons they have art, magic, and the soul of the city itself.
