Whitewater: A Thriller While searching for his parents' killers, ex-Navy SEAL captain Adam Weldon encounters a ruthless drug cartel intent on killing him, a gambling casino for the super-rich run by a radio preacher, a host of motley river guides, and a succession of hair-raising challenges both in and out of the whitewater rapids of the Kern River. This thrilling page-turner also provides a powerful, almost tactile experience of the magic and beauty of rivers--and is in essence a celebration of nature and life itself.
