In this book Robert John Langdon explores the possibility that when the ice finally melted and rather than leaving the land mass we now know as Britain it did, in fact, leave a collection of smaller islands caused by flooding as the land was still below the water table. Quite remarkably, this book shows that Stone Age Man survived the Ice Age and the great flood to go on to develop into a great civilisation - to date, an unknown civilisation which lived on these waterways which they used to trade and facilitate in the construction of magnificent stone monuments, such as Stonehenge that have lasted 10,000 years. Revisiting accepted archaeological, geological and topological findings Langdon has been able to write an astonishing hypothesis with compelling new proven evidence that not only re-writes our understanding of prehistoric Britain, but our view of the ancient world!
