Is Stonehenge a stone hinge?
As early as 10,000 years ago, early man knew of parallel universes. Not from quantum theoretical models but from face-to-face interaction with their denizens.
Over the last 30 years, television series and movies focused on the public's thirst for inexplicable phenomena. The growing number of books devoted to works explaining everything from UFOs to Stonehenge are testaments of continuing and increasing interest.
Each theory is specialized, honed to explain a specific mystery. Each generates more opponents than supporters. What if a single theory unified and explained a majority of these enigmas? What if the same theory reached back into our past and demonstrated ancient people dealt with these same mysteries? Otherworld presents such a theory, a theory born from a single question: What if Stonehenge really was a stone hinge?
