I used to enjoy Clive Cussler's novels, especially for the perilous situations the heroes would be trapped in and the inventive solutions leading to their escape. However, this story was just too over the top. Cussler's books are becoming more and more unrealistic. Honestly, a country like Argentina discovering oil in Antarctica, developing oil rigs and no-one ever knew about it. Please!!!!!! And desecrating a World Historical SIte to get skeletons to fool their captors. Not impressed.
