Forbidden Knowledge: Second Edition

KATHLEEN MARDEN'S amazing life as the niece of Betty and Barney Hill, the first scientifically investigated case of alien abduction, sent her on a lifelong search for answers. Her extensive investigation of their events developed into a career as a respected UFO investigator, researcher, author, and leader in her field. She has devoted years to investigation, research, and experimentation always following the evidence wherever it led and sharing her findings with her readers. When she discovered information that transcended the limits of conservative Ufology, the information she possessed was no longer acceptable to self-appointed gatekeepers who sought to control the narrative. However, the investigation of unexplained phenomena is legitimate in a free and open society, and you the reader deserve access to the truth. This is her story. Price includes shipping in the USA.
