For centuries, the Great Pyramids have fascinated Mankind; every year brings a batch of new theories, from the plausible to the absolutely bizarre. One lone seeker, after more than thirty-seven years of study and research, has at last managed first to understand and then to prove what lies behind this greatest of archaeological mysteries: a message of paramount importance for all mankind, through time and space. Its key - and its heart - are the Great Pyramids of Egypt. From China to Peru, from Egypt to Mexico, throughout the Middle East - through the world's oldest, most enigmatic and often most beautiful sites - the director has spent six years of investigation, guided by his anonymous informant, verifying his discoveries one by one, and meeting the planet's most eminent scientific and technical specialists. The result will shake the history of mankind as it is taught to its very core, and revolutionize Egyptology entirely. A great odyssey along a breathtaking route rich in staggering imagery, an extraordinary scientific leap and finally a revelation as unexpected as it is spectacular: the message bequeathed to future generations by these mysterious builders.
