Ex-deniable operator Nick Natural stone seems to be living his dream, not really a care in the world as he steers his camper van round the surfing and parachuting paradise of Australia, a board on the roof, a freefall rig in back of him, and a beautiful young backpacker at his side.

But when he sees a news survey of the massacre of females and children inside a terrorist outrage the other side from the globe, long-suppressed memories are triggered, and Nick has learned he must risk everything to settle a longstanding debts of friendship.

As events unfold in the bleak, medieval villages of Georgia and teeming roads of contemporary Istanbul, Nick finds himself catapulted once again in to the murky, clandestine world he thought he’d left out – a global in the grip of nameless opponents who linger in the shadows, and stalk the corridors of power…

Hurtled at breakneck speed through a deadly landscaping of greed, violence and ever-shifting allegiances, the reader will certainly be still left in without doubt that McNab may be the master from the genre – and Aggressor displays McNab at his searing, blockbusting perfect.
