Richard Hoagland, the author of this book, was at the time a NASA employee who became intrigued with the face and as he was to discover later, the whole eerie artificiality of the site known as Cydonia.

Natural phenomenon or artificial construction? The face has led to much speculation, however as this book points out there is more to Cydonia than the face alone. There are a growing amount of strange objects on Mars that seem to display signs of planning and construction.

The deeper you delve into the subject the more you begin to believe, at some point in Mars history, sentient life must of existed, "How long ago?" "What happen to them?" and "Who were they?" We'll probably never know.

This is a serious work, at over 400 pages long it is not for the causal or light reader, but if you stick with it, it becomes a fantastic read as to how NASA work and you do begin to question why more is not being made of this discovery. What do they have to hide?

Mars although the theme of the book is not alone in being scrutinised. Jupiter, Saturn and Neptune also have some strange secrets to reveal. Our closest companion the Moon also gets a mention and that reveals the biggest surprise of all.....
