This is the second book ive read by Cussler and it hits the same levels as the last. Dirk Pitt (a diving James Bond wannabe) returns in another totally unbelievable and yet thoroughly entertaining adventure that stretches across North America. This time the President has been kidnapped and everyone's blaming the Russians but is there someone else involved in the plot? Cussler has a great knack of weaving different characters together. Enjoyed it!
