[Q]: What a disappointment. This book is about 50% self-centered travelogue and 50% teasers about the mysteries. I expected a book full of archeological information about cities and cultures that have long since disappeared, but instead got embarrassingly ridiculous chit-chat and superficial explanations. I wanted scientific information, not a book that tends to explain most of its mysteries via levitation and alien beings!
[A]:
Negative
