The Farthest Shore, is the story of Alex Roddie's trek along Scotland's remote Cape Wrath Trail, one of the UK's toughest long-distance trails.
Alex is a highly experienced adventurer and author, writing for both The Great Outdoors magazine and the venerable Sidetracked.
As a digital native, he got to wondering whether his ever-connected online lifestyle had something to do with the gnawing sense of anxiety he constantly felt.
So, in a remarkable experiment, he set out on a second trek along Scotland's remote Cape Wrath Trail. This time, in the middle of winter and without the use of social media or the internet.
The results were perhaps surprising.
