This book looks at cults, secret societies and ancient orders around the world. It details cults such as David Koresh and The Branch of Davidians, Aum Shinrikyo , Jim Jones and The Peoples Temple and Heavens's Gate. It looks at ancient orders like the Freemasons, The Illuminati, The Spanish Inquisitions and The Knights Templar. Modern secret societies like the Ku Klux Klan, Skull and Bones and The Raelians are also covered. It’s quite an informative book that covers the origins, pivotal points and downfalls of these groups. It goes into details with the cults; some of the details he shares about the cults are unsettling. It’s not as quite as extensive when it comes to the ancient orders and secret societies, so further research is required in this area. The author does provide (a few) sources to his writings. The book also contains high-quality photographs and ancient pictures that is referred to throughout the book. Overall, I enjoyed reading this book. The author doesn’t take himself too seriously and there’s some lightheartedness to his writings, which kind helps for some of the disturbing details in the book.
