Okay, so, Starship Troopers, The Forever War, Old Man's War. Classics in the citizenship / military commentary through science fiction genre. There are others in this genre, but these are the ones that come to mind. There is a strong likelihood that in upcoming years, The Light Brigade will be in that short list of classics in the genre.
Similar to The Three, this book follows a newly enlisted grunt, Dietz in this case, through basic training and the first hit of war, all while describing the world, the history, the conflict. Of course, we learn more of the motivations and history and dystopian nature of the world as the book progresses. Despite the grim beginning, the book has a "happy" ending (as well as a book about war can be "happy"), which I understand, even if most of my recent readings have far less ... uh, happy endings. Natch.
What we do have in this book is the commentary on the military, citizenship, human nature, war, corporations, capitalism, power, and, sure, socialism. Even Frank Herbert and Ayn Rand make entrances.
Several things make Hurley's world building so compelling in this book: the complete and total mis-visualization of who Dietz is (brilliantly done), the mind-f--- that the plot twists and turns through, and the way the story telling weaves with the commentary so subtly that you forget the philosophical commentary parts of the book (yes, yes, except for the three pages of in-your-face philosophy dump that pales in comparison with Galt's 50 page radio speech (which can be totally skipped if you ever do read that book)).
Enjoyed the book. Will gladly read more of Hurley's books, looking forward to them also. Recommended.
