First of all, for me, Andy Thomas is a brilliant writer. His writing is educational, humorous and expansive. This little book is a great intro to the subject of crop formations. I appreciate the intelligent approach to a highly debated subject. I find there is a lot of misinformation out there and am glad for the simple clarity in this book. So whether you are just hearing about these or have a full library on the matter, it is a beautiful addition despite being written several years ago. The quality of printing is exceptional too! I find the line of Wessex books to be lovely. Enjoy!
