The islands of the Outer Hebrides are home to some of the most remote and spectacular scenery in the world. They host an astonishing range of mysterious structures - stone circles, beehive dwellings, holy wells and 'temples' from the Celtic era. Over a twelve-day pilgrimage, often in appalling conditions, Alastair McIntosh returns to the islands of his childhood and explores the meaning of these places. The book is a walk through space and time, across a physical landscape and into a spiritual one.
