I started reading A Game of Thrones based on the online discussions that took place at First Draft during the HBO series' first season. I'll be picking up the second book this week.
Like most good science fiction and fantasy, George R. R. Martin's books go beyond the story on the pages and serve as allegories to our world. Like the best science fiction and fantasty writing, it does this in ways both subtle and sublime, and avoids the hokiness of smacking the reader over the head with some sort of message.
So it isn't a surprise to me that Foreign Policy magazine took a look at the series through the lens of international relations, or that Wired breaks down military strategy.
