I'm interested to see what you think. The story is intriguing, but I have a hard time believing her "channeled" information. One thing I suspected was that the material she learned emerged in her visions, but the novel material that came to her was strictly something made up by her mind.
I think she was quite sincere and quite well educated... but I think she fell into a mysticism trap and went from reality to fantasy.
On the other hand, I haven't read the book (only reviews of her life.) Please do tell us what you think of it!
