Gulag, Book 2: Oil King

The golden touch... Hank Wylie was a hedge fund billionaire who designed and sold complex derivatives. After thousands of investors lost their life savings, Hank was sentenced to two years in Federal prison. When the prisons are emptied into Arizona, Hank tries to survive and rebuild his fortune in a world without money. Arizona is evacuated, and the entire U.S. prison population dropped inside. With high-tech armor suits producing food and water, prisoners are free to make their own rules. The gulag began as a dream of the world's richest man, but it was all a con. John Harkin didn't care about ridding society of criminals, he was trying to save humankind from extinction.
