Book excerpt: The Pacific Crest Trail runs 2660 miles, from California's border with Mexico to Washington's border with Canada. To walk it is to undertake a grueling test of body and spirit. In Americana, cartoonist Luke Healy accepts the challenge. This intimate, engaging autobiographical work from an Irish visitor to the United States recounts the author's own attempt to walk the length of the USA's west coast. Healy's life-changing journey weaves in and out of often humorous reflections on his experiences in America and his development as an artist, navigating both the trail itself and the unique culture of the people who attempt to complete it. For fans of Cheryl Strayed's Wild.
