I have read a great many criticisms of this book by people who either expected it to be solely about the PCT itself, or were offended by the author's use of coarse language and discussion of her sexual proclivities. And that's fine; all of those readers were obviously seeking something other than what this book had to provide. Myself, I enjoyed it from cover to cover. A longtime lover of the PCT, I already know about the trail from end to end. I was more interested in how the author used a rather spontaneous journey along the trail to help herself face demons and come to grips with her mother's death. There are moments where her emotions are so clearly spelled out on the page, and then there are times where you have to read between the lines. But every step of the way you're alongside her, watching as she learns to accept, to embrace, to let go, and how the PCT weaves through that.
This is a book I will most definitely read multiple times over the years. I almost regret buying it in Kindle format because I can think of at least five people I'd love to loan it to and demand they read it immediately.
