Query: Who needs Clive Cussler??? As long as I have Jack Du Brul, I don't!

This might be my favorite of his books. I read one written with Clive Cussler, then I read every other one in the series. Went through withdrawal! Then I got every book I could find by Jack Du Brul. None disappointed me in any way.
