Children of Ptah. Third Manuscript of the Richards' Trust

Egyptologist Joseph Richards stumbled across something that simply set his mind ablaze. His hypothesis was so contrary that if it became public his banishment from the academic world would be assured.
Simultaneously, highly classified evidence lent credence to Richard’s position, which ultimately allowed him and his partner Gregorieva to venture back farther in time than any had ever attempted before – all in search of a man named Ptah.
Meanwhile, there are others who secretly covet the Soap Bubble technology, who are willing to do whatever it takes to get it, and who even tried to steal it - twice.
Children of Ptah. The Third Manuscript of the Richards’ Trust completes the temporal adventure trilogy of Professor Joseph Richards.
