I know I'm a sucker for hiking tales. I'm a hiker, and I read most things on the topic I can get my hands on. Within that body of hiking literature, I'd say this one is fairly interesting and motivating. It does make me want to hike the GR10; after I finished the book I went right out and bought the trail guide. You should not, however, expect this to be Bill Bryson hikes the Pyrenees. That's not the author's intent. Instead he takes you on his 50-day trek, full of gorgeous scenery, interesting characters, the usual hiking snafus and problems, and some physical misery. I enjoyed it and will probably listen again, this time with guide book in hand.
The reader did an excellent job. And, thank heavens, his pronunciation of the names of French towns was accurate---otherwise the listening experience would have been difficult.
My only caveat is that the author seems concerned you'll think he and his hiking partner may be lovers rather than just friends, so he makes any number of jokey references to the fact that they are not. These jokes become annoying fairly quickly. Aside from this bit of "homophobia light," I enjoyed the book immensely.
