Max McLean is a strange kind of civilian. Spy, assassin, sniper: he's good at what he does. Officially, he doesn't exist. But that's how the British government likes it - denying any knowledge of the missions he's sent on to keep us safe. Max has never before had cause to question his orders.
But when it turns out that a target in Colombia isn't who London says she is, not only does it seem of no concern to his superiors, but they take issue with Max's decision not to pull the trigger. Disillusioned, Max accepts what's presented to him as his final job. Immediately he's sent to see one of his comrades-in-arms and the bravest man Max has ever known: a giant of a man now locked away in a military research facility neither as patient nor prisoner - but curiosity. The reason for his incarceration is as simple as it is inexplicable: fear. Something the battle-hardened Special Forces veteran experienced during an operation in West Africa has destroyed his mind. Now he's a wreck, living in mortal terror for himself, his loved ones and his country. Max is ordered to investigate; to find and eliminate the threat. Ahead of him lies a remote jungle mining concession hidden from prying eyes; an old enemy; and a dreadful, breath-taking collision between cutting-edge science and evil beyond imagination. Acting alone, without back-up, he lands in Freetown with his friend's last words ringing in his ears: 'They're coming, Max. They're coming.'
