Book #7 was Pacific Vortex!, the first Dirk Pitt story by Clive Cussler. The back of the book reads:
Dirk Pitt’s first, most terrific adventure! Dirk Pitt, death-defying adventurer and deep-sea expert, is out to the ultimate test as he plunges into the perilous waters of the Pacific Vortex â€” a fog-shrouded sea zone where dozens of ships have vanished without a trace. The latest victim is the awesome superb Starbuck, America’s deep-diving nuclear arsenal. Its loss poses an unthinkable threat to national defense. Pitt’s job is to find it, salvage it, before the sea explodes. In a furious race against time, Pitt’s mission swirls him into a battle with underwater assassins-and traps him in the arms of Summer Moran, the most stunningly exotic and dangerous toward disaster, Clive Cussler plummets his hero onto an ancient sunken island-the astonishing setting for the explosive climax of Pacific Vortex!
This was the first Dirk Pitt story Clive Cussler wrote, though it wasn’t published until 8 years after the first book was published. Dirk is a little rough around the edges here, but he’s lacking a little of the machismo/misogyny that plagues him in the first few books in the series. This is a good thing. In fact, Pitt uncharacteristically falls in love in this book, and you have to wonder if that puts his behavior in the next several stories in a different light. Regardless of Pitt’s behavior with the ladies, this story gives you exactly what you expect from Clive Cussler — action, adventure, and a completely unbelievable plot, complete with pontificating bad guy. All things I love when Cussler is involved. Overall, this is a quick, fun read.
