Strike Back: A war hero. A broken veteran. A lethal crisis.

Two soldiers. John Porter - seventeen years ago he was one of the SAS's most promising young soldiers. Now he's a broken man: a drunken tramp living rough on the streets of London. Sir Peregrine Collinson - Britain's most decorated military hero, a bestselling author, and the Prime Minister's personal envoy. In Beirut, a brilliant young Sky TV reporter, Katie Dartmouth, has been captured by a ruthless gang of Hezbollah terrorists. She is to be executed live on television unless British troops are withdrawn from Iraq. A nation holds its breath and the Government is teetering on the edge of collapse. Both men believe they can save her. But only one of them can reach her. Their paths last crossed seventeen years earlier. Now, they are about to face each other again. And the strike back is about to begin.
