Some say Cussler writes for men, but I disagree. What red blooded American woman would not want to spend the night with Dirk Pitt? He is the original man's man. I have to admit, I have not been as enthusiastic about the Kirk Austin series, but it started to grow on me and I think "Polar Shift" maybe as good as the best of the Pitt Series. I won't rehash the plot except to say the plot has to do with some bad guys figuring out a way to switch the magnetic poles causing real havoc for the planet (I guess this has really happened naturally in the past, which I did not know). Of course Kirk and his NUMA crew are the only ones who can stop the evil madman. I got caught up in real suspense here, there are some unexpected twists, and this time out success is not guaranteed-at least I did not think so. Most of you who read Cussler know what thrilling, adventure to expect, and you won't be disappointed here.
