Problem: Review: This book is a rarity in UFO literature, primarily b/c most UFO books present their information in dates and names and places and events ... in a sense, completely without any feeling or substance beyond the 'happening.' The shocker of the ending of THE MOTHMAN PROPHECIES you already know if you read the 1st chapter, but, as you've been drawn further and further into the lives of the main participants, the ending hits you like a sledgehammer b/c you've spent the last 250 pages forgetting all about it. More UFO books should be written with this humanistic approach; perhaps then the subject wouldn't be so taboo.
Polarity: Negative
Solution: False
