Book excerpt: Since the publication of The Blackhouse in 2011, the books of Peter May's groundbreaking Lewis Trilogy have enthralled millions of readers around the world with powerfully evocative descriptions of the Outer Hebrides. From its peat bogs and heather-coated hills, from its weather-beaten churches and crofters cottages to its cold clear rills choked with rainwater, the islands off the northwest coast of Scotland have been brought to vivid life by this accomplished novelist. Now, Peter May and photographer David Wilson present a photographic record of the countless locations around the Hebridean archipelago that so inspired May when he was bringing the islands of detective Fin McLeod's childhood to the page. From the tiny southern island of Barra to the largest and most northern island of Lewis, travel the storm-whipped North Atlantic scenery with May as he once again strolls the wild and breathtaking countryside that gave birth to his masterful trilogy of novels.
