Query: A par effort for Cussler

Although this book contains all of the same ingredients for success, I felt that it was slow at some points and more unrealistic than his other great ones. Dirk Pitt is once again the man we all want to be, but I just wasn't swept away by the moon colony and the hunt for La Dorada. I also wasn't pleased with the ending. Cyclops is a fast and exciting read but fails to grab the reader's attention as easily as his past gems
