Circle in a Spiral — Arthur Wiederhold

The steamy Guatemalan rainforest is the setting for this romantic adventure in the tradition of Indiana Jones. While exploring a little-known area of the Yucatan Peninsula, a team of archaeologists stumble upon the ruins of an ancient city that was built by a previously unknown civilization. As they explore the enigmatic ruins, they discover things that rock the scientific establishment to its foundations and forever alter the history of mankind.A thought-provoking adventure story that takes current theories of the origins of civilization and runs with them. This could very well change your views of man's distant past and the world at large.Another masterpiece by the author of The Reaper.
