Twenty years after The Great Global Riots and the collapse of humanity, Alex Locke struggles to save his family, and his home colony of Pena, from starvation.

When a letter from the corrupt Govern arrives dictating a game of survival penning local colonies against each other, Alex must trust a childhood friend, and seven others, on a certain death march to win the bounty or lose the only hope left in a war-ravaged world.
