the book is setup chronologically, from traveljournals.com (I think) which was written up and edited by a friend of his. This means the book itself is very much a fairly sparsely written and a basic, straightforward account of how he felt as the day(s) went by. There are a few stories here & there, but for the most part the book deals mainly with the physical cost of the journey. He does talk about the gear and what did and didn't work for him. I find it amazing that he got to the end despite the physical pain and the challenges he faced.
It is self-published (again, I think), so there are some errors and some lack of smoothness in parts of the book. I found the updates from later in life to be interesting. I also found his comment about thinking about the Appalachian trail every day to be interesting. The physical parts would be a spoiler, but I appreciated the fact that he talks about what it cost him physically and what it took for his body to recover.
Not a bad book, but lacks depth until the end, when he talks about how the book changed him and some aspects of his life that he wishes were different. Still a very positive person and he is planning to hike with his daughter at a later date, which is very cool. Worth reading.
