A Harvard psychiatrist, the author of A Prince of Our Disorder, presents accounts of alien abduction taken from the more than sixty cases he has investigated and examines the implications for our identity as a species. These mesmerizing and thought-provoking stories of alien encounters from a Harvard professor take you through actual case studies of people from all walks of life and ages who have had challenging, sometimes disturbing, and in every case, life changing experiences of alien abduction. "John Mack explores evidence of nonhuman intelligence like an attorney preparing for the 'trial of the century'--interviewing witnesses, examining physical evidence, consulting with experts in related fields, constantly questioning his own assumptions... As a story of one man's determination to bear witness to cosmic mysteries with extraordinary implications for the human future, Abduction is bound to become a modern classic" (Keith Thompson, author of Angels and Aliens)
