Query: Excellent Book About Alleged Alien Abductions

This is an excellent book by a Harvard reasearcher who is openly skeptical of UFO's. It is about folks who sincerely believe that they have been abducted by aliens. They are by and large average, sane people.Clancy notes that the abduction stories are consistently the same no matter who is being interviewed. She maintains that this is because of hypnosis, science fiction and folks reading of/watching TV shows about other folks who claim to have been abducted.The focus of this book is if the folks were actually abducted, but why they believe that they were.
