To Fight For (The Killing Machine, 3)

Fighting is all he knows. Before he became an assassin in London's underworld, Joe was a bare-knuckle boxer. Before that he was a soldier. But nothing prepared him for this. Revenge drives him forward. On the streets of East London, a turf war is raging. And Joe has no choice but to join the fight. It's the only way he can find out what happened to the woman he loved—the only way he can bring her killers to justice. Either they die, or he does.
