Unlike Map of Bones, this book followed Rollins' typical style more closely. Intrigue and mystery were evenly matched by action and great characters. Like all the thriller-authors I like, I think he gets kinda carried away with the romance between characters, but that probably helps his books sales. It's easy enough to skip those parts. :-)
This book captured the feel of a good Cold War story, as Russians and Americans are in conflict. But unlike most Cold War stories, it isn't really clear who the bad guys really are. The heroes get sucked in to the situation, and it's always easy to cheer for an innocent bystander who gets swept along for the ride.
Ice Hunt involved several opposing forces, back-stabbing each other along the way, as well as a force of nature that I won't ruin for anybody. I absolutely loved the force of nature, but I'm geeky that way. Great stuff, my favorite Rollins book so far.
