In his quest for lost civilizations, American anthropologist, Dr. Jacob Walker, begins researching the strange stone walled circular structures scattered by the thousands across southeast Africa. The South African government believes these circles of stone are just a bunch of old cattle kraals. The evidence suggests otherwise.The work begins at the enigmatic site known as "Adam's Calendar." Is this just a natural stone outcropping, another unexplained megalithic site like Stonehenge, or is it the birthplace of humanity? Could this region be the ancient realm of the Queen of Sheba or the location of King Solomon's mines? Is there a connection to the strange stories about Nephilim and the lost kingdom of Atlantis? Why is someone interfering in their research? For Jake and his friends the answers could come at far too high a price. Who will live and who will die among the mysterious-Circles of Stone?Based on actual research being done today in southern Africa, this high octane thriller picks up where Outback of Beyond left off.
