Life in SoCal in 2195 is controlled by a corporatocracy.

Elsa scavenges twenty-first-century trash, living on the edge of starvation in this ruthless world through her grit and instincts.

When she unearths a metal tube containing maps to six Doomsday seed bunkers and a silver key, she dreams of renewable sources of food and a life based on more than subsistence, but GreenCorps will stop at nothing to acquire her find. Accused of theft and beaten half to death, she escapes with a handsome train hopper. They seek the long-lost bunkers, hoping to break GreenCorps' monopoly on food.

Along the way, they receive help from a teenage pickpocket, a solitary widow, and a rebel leader. If this rag-tag group of lonely misfits cannot reclaim the tube and find a way to distribute the seeds, GreenCorps will continue to choke out any chance of a better life.

Hop aboard this thrilling dystopian train-hopping adventure with Switching Tracks.
