This book contains all that is today, in 1993 at least, known about crop circles: introduced, beyond splendid photographs, also by all the possible interpretative hypotheses. Particularly fascinating is Hesemann's approach that features intelligent communications from extraterrestrials, wanting to make us understand something. Following the Author, they are symbolic, not readable like an alphabet but destined, instead, to speak to the right side of our brain: the intuitive, creative side of us. Maybe they are messages for our own unconscious, in order to produce an inner change through the beauty and the harmony.

Is it possible that the mysterious crop circles are hoaxes, as the press says? After three years of researches, Hesemann demonstrated that it is not the case, revealing the reasons for which the authority has tried to trick the public and hide the truth. American scientists have uncovered, from plants sampled from the remarkable circles, physical and genetic anomalies, alterations that may be due to microwave radiations. But who is the executor? Photos, investigations and intriguing evidence come one after the other; Hesemann fascinates us with the much waited answer to this and other questions.

Hesemann is a good ufologist, widely documented, but I wonder if the book's conclusions'd be the same today, after circlemakers and Hasselhoff controversy.
