Surprisingly, given the nature of a number of the reviews I've seen for this book, I really enjoyed it.
Let me rephrase. I opened it up briefly to peek at it and see what the writing was like, and ended up carting the book up and down the stairs with me while I got ready for work, reading over breakfast, reading the moment I got home, and reading well past my bedtime to find out what happened. I loved this book.
I think the author did very well communicating the depths of Green's lack of understanding about the world around her; I think he did well following her journey to understanding about her own nature; I think the journey itself had mythic qualities that not only follow the quintessential hero's journey, but the tales of folklore.
I also loved the writing style. For some reason, I found it almost lyrical and meditative.
