Five white-water rafters, two FBI agents, and bad boy Ace Goodall and his girl, Carla travel down the Unegama River in the Appalachian Blue Ridge Mountains and are terrorized by man-size vampire creatures. There was enough bickering going on between the macho characters for me to hate them enough that I was looking forward to them biting the bullet. Unfortunately, the characters I was rooting for did also. Think of Deliverance only the oversexed hillbillies are now winged vampires out for blood. I liked that Scott Nicholson wrote a review on himself why he wrote the book.
