Dr. John Mack was a man of deep sincerity and intelligence, a Harvard professor of psychiatry, a Pulitzer Prize winning author, and an original thinker, who had the courage (some of his academic peers claimed recklessness) to devote his considerable talents to a serious, prolonged study of the abduction phenomenon — by spending time, and offering an empathetic (yet appropriately critical) ear, to those claiming to have had such extraordinary experiences. This book is, I think, worthy of the man – a well-researched, thoughtful and sensitive study of this complex character — interesting from beginning to end. The narrator is very well suited to the subject.
