I approached this book with a very open mind and did find myself questioning a lot of accepted facts about our history. The chapters on Egyptian engineering and on human evolution from hunter gatherer to farmer are exceptionally good and thought provoking.
However, this is not a coherent book so much as a collection of articles from "Atlantis Rising" magazine, and as such it is very disjointed and often repetative. Some "chapters" are little more than interviews with individuals who have a book to sell and who only talk in vague terms about what their book is about.
The main reason why I only gave this book three stars is because it could have been so much better. Some of the chapters talk about extremely interesting subjects ( such as the Olmec stone heads ) and ask very interesting questions ( why do they depict African faces, how were they carved and moved etc ) which it then fails to answer. When an answer is provided, it almost inevitably is ridiculous in the extreme ( eg: music was used to levitate them, or space men did it and ran away- I am not joking, these are put forward as genuine theories ). I am open to the idea that maybe mankind did have help to jump from caveman to the bronze age, maybe there was a civilisation before accepted history began, maybe the Egyptians did have advancing cutting technology to achieve the amazing cuts and right angles visable today. However, this book asks many questions but provides very few plausable theories to answer them. It all too often makes huge jumps of faith which I found very lazy and academically shallow. For me, the book was worth the cover price for the two or three good chapters in it which are well written and thought provoking, but the authors need to get away from the conclusion that anything they cant explain must have come from Atlantis.
