Three hundred years ago humanity almost eradicated itself…almost, but not quite. As is the persistence of human kind, we hung on; we survived, but the world as we knew it was changed forever. The exact details of what happened have been lost in time. All we know is that this is our world now and we have no choice but to live in it.

Oz and his sister True have been travelling for as long as they can remember. Ma feels that staying on the move is safe, that it prevents them getting lazy and complacent. It’s a better way to avoid bandits and raiders, a more effective way to stay alive. But the thing, the person that protects them is Oz – a lethal fighter who will go to any lengths to defend his family.

Oz makes money from cage fights while dreaming of a better life for them all – a home where they can be truly safe. True dreams of freedom, love and hope and just when she thinks she’s found it their world is turned upside down and they are forced to embark on a journey that rips them apart. For when True is taken by an unknown enemy Oz must enlist the help of a man from the shadows to save her.
