It's a read

Polar Shift is entertaining. Typical Kurt Austin Adventure - save the world without losing sense of humor while getting the pretty girl. The general concept was quite interesting and a recent topic on the science channel.

In the how I'd improve the book column - maps, a little more effort on the history and science of the main theme and less on the gimmick near the end and more proof editing (page 477 "He stared" not "Her".)

2 1/2 stars.
