In a world controlled by corrupt government officials and gangs, staying alive is a daily challenge. When their parents are killed as part of a population control scheme, twins Kalyah and Caze Tamesis know they're next, leaving them with one choice: to run. A hundred miles from their hometown, they meet Morgan Kimber, the leader of a mercenary gang called The Black Guard. She offers them a place in her gang, but in this new life, survival comes with a price-it just might not be a price the twins are willing to pay.
