Nathan K - he can hold two souls in his body. If he dies, he loses one yet lives on with the other. As long as he replenishes his second soul, he cannot be killed. Nathan K is immortal. ON THE RUN After killing Russo, one of the top Immortals, Nathan needs to get into the United States to hunt down his final target - Larkin. But such violent actions have equally violent consequences. Larkin has put out a bounty and sent his best people after Nathan. With every avenue of escape closing off, Nathan and Robin find their way to Australia and hope to smuggle themselves to the States undetected. Only problem - their point of contact turns out to be in even greater trouble than Nathan. When those problems catch up, Nathan finds himself locked in a struggle to fight his way toward freedom while trying to keep his whereabouts off Immortal radar. Not easy to do while shooting up storefronts in Brisbane. Making it even harder, a biker gang and a local crime family turn their focus onto Nathan. And that's all before Robin is taken hostage.
