Meh. The author draws interesting parallels between Martin‘s work and historical events, but if you have any familiarity with European history, you know this stuff. Also, where have all the copy editors gone? Grammatical errors he‘s too fond of semicolons), misspellings (“poll” when it should be “pole,” “grizzly” in place of grisly,” etc.). Not at all deep, but useful for pointing out Martin‘s inspiration/sources.
