S.A.S.

When the mission ends, the real war begins.

Captain Jack McCormack has lost everything that mattered.

His partner, Lieutenant Michelle Richards, was killed during a covert operation in Iraq-her death a brutal reminder that even the best can fall. Months later, his ASIO team-friends, family in all but name-were systematically executed during a routine bonding session at a suburban paintball park. It wasn't an accident. It was a message.

Now isolated and hollowed out by grief, Jack tries to disappear into the shadows. But when a dangerous new synthetic drug called Supernatural starts flooding the city streets, he's forced back into action. Jack knows this drug. He's seen what it can do-what it did before, in a mission buried so deep it was meant to stay forgotten.

With ASIO compromised and political forces tying his hands, Jack turns to the only people he can trust-his retired SAS brothers, elite operators with scars of their own. Together, they launch a black-ops investigation to uncover who's behind Supernatural... and why the same shadows keep reaching into their past.

But some ghosts aren't just memories.

Some are still alive.
