Query: We need dirk and al back!

This book lacked all of the literary plot and depth that made all other of Cussler's books a success. The suspense was lacking, the new young characters seemed stale already, and the threat of the opposition was too easily thwarted. We need something that threatens the world, we need more womanizing, we need more cars, we need Dirk and AL!
