In 2069 A.D. a divided nation and the world are recovering from a devastating climate change event. A cabal of wealthy families controls the Eastern industrial states. The Midwest has been ravaged by cycles of flood and drought, leaving many to rely on Christian charities. The California Federation of coastal states has fared well under governance by an artificial intelligence that has walled off the state behind a deadly high voltage barrier and killer drones. When a charismatic preacher declares the imminent second coming of Christ will occur in California, a caravan of 100,000 desperate Christians is determined to defeat the border wall and enter their promised land. Their fate hangs on the actions of a small band of young operatives whose lives will be shaped by politics, romance and the operatives of the state who pursue them.
