Ex-Australian Specialist Response Group leader, Tim "Harry" Harrigan, has been running covert ops for almost a decade. A lone wolf, he's single-handedly taken down terrorists and national security threats, or so he thinks. He's been in the game far too long, and when he sees a familiar threat, he knows his time is up.

Asher Garin is a dangerous man. A man without loyalty, a man without a nationality, without a country, without a home. He's also a mercenary for hire to the highest bidder. His next job is a face he recognises, and after a tip-off, he learns he too is a marked man.

It's a different game now, and Harry and Asher have a better chance at surviving if they stick together. But it's not just the game or the rules that have changed. The stakes have too.

Because on their own, they had nothing to lose. Together, they do.
