It's hard to go wrong with this subject matter, and I would recommend this book wholeheartedly.
But that said, I was a little disappointed in the book, not for what was in it, but for how much more she could have told us. The author has had a rare experience -- who else do you know who has lived on a houseboat in a swamp, without electricity or most modern conveniences, for a decade? Yet I was left feeling that she only related the bare minimum about her years in the swamp. Part of the problem is that the first half of the book appears to contain only her previously-published articles about her life at that time from a small regional magazine, and they are short and lacking a lot of detail. I'm left thinking how much better this book could have been if she had gone back and fleshed those out, adding more information and context. She doesn't discuss how it felt to adjust to such a rustic life, her relationship with the man she shared this life with, or any problems that they encountered, other than their dislike of returning to civilization for supplies every so often. In other words, she doesn't inject much of herself into her descriptions -- her feelings, her hopes or fears.
The second part of the book talks about temporarily working as a cook on a river boat, meeting the man she would later leave Calvin for, and her life since she left the swamp. In many ways, this is the more descriptive part of the book, especially as she details honestly the boredom of riverboat life and the pain of falling in love with another man. I was left imagining what could have been if she had applied the same descriptive style and writing technique to the earlier part of her work.
Again, I am glad I bought this book, but if the author had spent the time beefing up her earlier articles in the first part of the book, when the subject material is far more unusual, I would have given this book a higher rating. There aren't many people who have lived a life like hers, and it's a shame that it isn't more thoroughly described during her swamp years.
