All over the world, quite independently, thousands of people are claiming they have been abducted by aliens. Often these people are ridiculed by the media, regarded as unblanaced by scientists and ignored by the governments that are supposed to protect them – in spite of this, they persist with their claims. Former UK Government UFO investigator Nick Pope has written the definitive book on the alien abduction mystery, delving into folklore, the contactee movement, and more modern claims that people have not just seen UFOs, but encountered extraterrestrials. He also examines the reaction of governments, and of the scientific community, as well as examining the world’s most famous alien contact cases and highlighting the common threads that bind them together. Pope devotes a significant portion of the book to detailing a number of cases that he investigated personally, before drawing things together by discussing the various theories that might explain what lies behind this fascinating mystery.
