This is an extraordinary story. Four soldiers, each a hero of recent conflicts who has suffered devastating injuries, taking on the challenge of a four-week trek, unaided, to the North Pole. The expedition will see the adventurers cover 300 miles of frozen Arctic Ocean, navigating vast swathes of ice rubble and pressure ridges. And all the time, they'll be keeping their eyes peeled for Polar Bears. Pulling in excess of 100kg each, and with every step fraught with risk, the participants' resilience will be tested to the limit. Each of the men tells their personal story in this book, along with that of the extraordinary expedition itself – the rigorous training, the meticulous preparation, and the final, awe-inspiring voyage across the ice.
