Join Christian Lewis as he walks the entire coastline of the UK - his dog Jet in tow - and rebuilds his life, step by step. With a foreword from longtime supporter Ben Fogle, Finding HIldasay is his inspiring true story of reconnecting with nature and finding hope along the way.

Ex-paratrooper Christian Lewis had hit rock bottom, suffering with depression so severe he would shut himself in his bedroom for weeks. Then while surfing - his sole respite - he cast his eyes along the coastline and realized it was the only place he really wanted to be.

Then, Chris made an impulsive decision. He set himself a challenge: to walk the entire coastline of the UK. He gave himself a few days to rustle up a tent and walking boots, then left for good with just a tenner in his pocket and two days' worth of food. Little did he know at the time just how long it would take to cross the finish line - and the encounters lying ahead would turn his life around.

Almost six years later, Chris has navigated the West Coast, Northern Ireland, the hard-rock cliffs of Scotland and the perimeters of the Scottish Islands. He spent three months on an uninhabited island called Hildasay, with beloved dog Jet. It was there, the most barren his route had become, that he found within himself the pride and respect he needed - and his journey became all the more remarkable. Happiness and hope was just around the corner . . .
