Suspicion naturally arises when you read a promo line on a back cover that says, "This is the most important book concerning the Great Pyramid written in the last 20 years." In this case, however, it may be fact. In writing The Giza Power Plant, mechanical engineer Christopher Dunn reverse-engineered the Great Pyramid at Giza to discover its use. His startling conclusions blow the heck out of traditional Egyptology's rather silly notions that it was built with copper tools by a society that lacked the wheel. While revisionist pyramid studies are rife with ridiculous theories that give the topic a bad name, The Giza Power Plant takes into account existing fact and artifact without having to rely on unprovable assertions. A must-read for truth seekers who aren't afraid to consider the idea that Western culture of the 21st century may not be the pinnacle of human evolution and achievement. --P. Randall Cohan
