This book invites the reader on a journey into mystery and wonder. It pursues the great questions that have always troubled humanity: what came before us? What is the history we are unaware of? How did the flourishing civilisations of the past rise and then suddenly disappear? What are the hidden messages that our ancestors left us? This journey will touch on 52 locations, some of which are remote or inaccessible, rich in history and charm. Some host enigmatic presences such as the gigantic prehistoric remains of the English countryside; the underwater ruins off the coast of Japan; the inexplicable Nazca lines in the Peruvian desert; the timeless faces of Easter Island's Moai; the real Count Dracula's castle; and the deep waters of Loch Ness in Scotland that may be home to a prehistoric creature. The author's engaging and comprehensive text, which reflects the time he has devoted to researching the most fascinating mysteries of history, science and archaeology, will guide the reader on a quest to discover the characters, signs and ruins that paint a picture of a planet that is filled with puzzles waiting to be resolved.
