Just this afternoon, I was purusing a favorite online bookstore. I love to go in and just read the reviews. Noticed this one on crop circles tho I haven't read it, it sounds very interesting and informative.
NOTE: when you click on the link below and the page comes up you will need to scroll all the way to the bottom as the book is the next to the last.
Here is their review:
Secrets in the Fields: The Sciece & Mysticism of Crop Circles
Silva, who has worked in graphic design and advertising for most of his professional life, conveys his keen passion for earth mysticism in this probing examination of crop circles. He examines the history of crop circles, human interactions with them, their probable implications, and, in a section that is alone worth the price of the books for supporters, their effects on our current worldview. Silva also delves deeply into the evidence for crop circles' authenticity. In arguing that they are transhuman events, he discusses the role of electromagnetism and its effects, UFO phenomena and their relation to crop circles, the relationship between crop circles and healing, evidence supporting psychic ability, and language's ability to affect information consciously and subconsciously (this section is sure to stimulate those who suspect that crop circles are a hoax). Readers may be inspired to reexamine preconceived ideas, as Silva's explanations are detailed and well researched and avoid technical jargon. Footnotes and an extensive bibliography encourage further exploration.
