The Crystal City of Giza (Paperback) (ISBN-13: 9798272999368)

Beneath the Great Pyramid lies the the truth about humanity's past and its future. When Dr. Aris Thorne, Dr. Lena Petrova and Ben Carter, three archaeologists, descend into a pit within the subterranean chamber of the pyramid they do not know that what they will uncover can rewrite the history of the solar system. Hidden far below the desert sands lies a city of crystal and glass shimmering with alien technology - yet eerily empty. As the explorers activate the city's systems, visions begin to unfold before their eyes.
The origin of the moon: the creation of mankind by beings of unimaginable power: the death of life on Mars and the actual building of the Sphynx and the pyramids. The Great Flood that reset civilization and a vision of a future Earth on the brink of annihilation.
Each revelation brings them closer to a staggering truth, and a terrifying question: Why were they shown these events and will the city ever let them leave.
