I have mixed feelings about this book. I liked the occult bits of the story but got bored with the extensive look at the transhumans, their culture, religion, etc. It just seemed to go on and on.
I am not sure where I got the ebook edition that I read. I am pretty sure it came through Amazon but I can't tell for certain. The edition that I had was full of errors: run on words, broken words, misspellings (capital G's were consistently replaced with Q's and capital I's with T's.) and others. I realize the book is written as a diary and as such, some errors would be intentional. But, I don't think this is the case here. It looks to be a poorly done scan.
