In The Pyramid Code, a team of archaeologists discovers a hidden chamber within the Great Pyramid of Giza. Inside, they find advanced technology and a holographic recording left behind by a group of extraterrestrial beings called the Ankhor. The recording reveals that the pyramids were actually constructed as a means of communication with other intelligent life in the universe and that the Ankhor had visited Earth thousands of years ago and left behind the pyramids as a way to make contact with any other intelligent species that may have evolved on the planet. The team of archaeologists extracts the technology and the recording and brings it back to their research facility to share with the world. As word of the discovery spreads, scientists and governments from all over the world rush to study the Ankhor's technology and decipher their messages.
