A husband and wife team hike the Pacific Crest Trail from Mexico northward. The book is written by the wife. Along the way, they develop an extended trail family whose membership morphs as people drop out, skip sections, drop in, quit the trail, and meet for impromptu reunions along the way. The book captures the monotony as well as the regenerative essence of thru hiking: you hike all day, you eat, you sleep, and then do it all over again, day after day, week after week, month after month, mile after mile. If that bores you, don't read the book. If you've done any thru hiking, you can relate to the story and enjoy the book. By the time they reach Washington, the story becomes bittersweet: they will soon be leaving the trail and the trail has become their home, where they belong. They are no longer Erin and Carl, they are Hummingbird and Bearclaw. Home is a tent; the kitchen is a campsite, sometimes right on the treadway of the trail; the kitchen appliance is a backpacking stove. And there is a surprise ending.
I would recommend this book to my backpacker friends, but for those who have not done any long distance hiking or for those who get "bored" easily (boredom is from within you - it is your inability to relate to your environment), I would say "Read Dean Koontz, James Patterson, or Janet Evanovich" instead.
