See storyline above.James W. Hall writes a great thriller and I also think this is one of his best.From it's dramatic opening to its satisfying conclusion, `Blackwater Sound' paints a riveting picture of southern Florida. Thorn, a laid back individual that seems to attract trouble like a magnet attracts steel, returns in another very satisfying novel of adventure.Halls dialogue and narrative paint a vivid picture. The locales of Southern Florida along with the characters, makes this a very `hard to put down' book.Highly recommended
