Off the western seaboard of Scotland are hundreds of islands. Beginning on Arran, Jonny Muir sets out to explore these places with a single ambition: to reach the St Kilda archipelago, the islands at the edge of the world. On the way he attempts to finds his inner peace on Holy Island, takes part in a punishing foot race across the mountains of Jura, confronts the Inaccessible Pinnacle on Skye and walks the white-sand beach on Berneray. He encounters sharks and whales, discovers gory histories and follows in the footsteps of Boswell and Johnson, but island life is not without its challenges. 'Man-eating' midges live up to their reputation on Rum. An Atlantic storm threatens to rip his tent to shreds on Barra. Wicked weather lashes the Outer Hebrides, leaving his prospects of reaching St Kilda balanced on a knife-edge. An intensely personal account of a journey through some of Britain's most extraordinary landscapes. Complete with twenty five beautiful colour plates.
