Query: A Treasure

This is one of those thoughtful, carefully written books one must sit back and absorb. It doesn't have CIA agents named "Dirk" running around with beautiful reporters in stiletto heels. There's a unique, introspective quality and pensive theme throughout that, if you're listening, takes hold and carries you along. Granted, it lacks the thrill and excitement that people look for in a "good-guy-bad-guy" book. Instead, it's a treasure. That's why I read it twice, in fact, and enjoyed it more the second time.
