Right now, it's a free download at Smashwords.com, and $0.99 at Amazon Kindle (they don't allow me to make it free there).
What follows is the longer description:
The world of the late 21st century is divided between Greater China, the Western Block, the Islamic Block and the Southern Free States of Africa and South America. The Western Block is dominated by the multinational corporations, who have created a paradise for its citizens -- so everyone thinks.
Mickey O'Brien is the Eurasian, half Asian and half Irish. He has a problem with that, because all his friends are fully Asian. However, no one has actually met each other -- only their virtual projected images they show on their on-line classroom environment. He and his classmates meet each other for the first time as they go on a class trip to America. It turns out they all had things to hide.
In America, they accidentally discover what the Multinationals have been trying to hide. Their hover van is hijacked, and they are left trapped in the great American outback, a vast area of what was once U.S.A., now divided between countless republics. Some are Nazi, some are militant Christian and other redneck cowboy states, some Native American Nations, Mafia kingdoms, etc etc. The wild west is again wild. Once having stumbled in, can they ever find their way out again?
It's a story of finding out what's real, and discovering true faith as they become involved in an espionage war trying to prevent a Nazis takeover.
