Think of what normally would be an ending to a great series and now that this series will continue with 'Dirk's' and Clive's sons. It might not be up to Clive's standards but it gives an excellent start to Dirk's continuing the series. What I have worried about is the series ending with the death of Mr. Cussler or the killing off of the Dirk Pitt character. It will not come--THANK GOD!! Mr. D. Cussler thank you for continuing the most enjoyable book series I have read. I would also recommend ' The Quest ' by Giorgio Kostantinos. Another great action series.
