As usual, Clive Cussler and his son provided a great story. What was different, and quite enjoyable about Crescent Dawn Dirk Pitt 21 is that you think the story is done, yet there are pages left. So, you go along and come to what you think is the ending...again. But there was still pages left! And finally you come to the end of the book, and the storyline, and you want to just keep reading, but you can't. Excellent story, with many twists. I'm already starting on Cussler's another NUMA book. Ask our librarian...it's as though I can't get enough of these books.
