My opinion of this book is set in the shadow of the Gone series, of which I am eagerly anticipating the new book (just a couple weeks to go....)--so I worry that I'm not being entirely fair to BZRK. 
 This book is radically different from the Gone series. It is set in a fascinating alternate reality where nanobots are being used to modify human brains, and the story revolves around the war to preserve human autonomy and free will. 
 One of my favorite things about Grant's books is the moral ambiguity of the characters and situations. Good and bad are highly relative and shift throughout the book, even moreso in this series than in Gone. The characters are shades of gray, with some darker or lighter than others. This is the true brilliance of the BZRK story, since the "bad" side ostensibly wants to help (or force) humanity into utopia, while the "good" side is fighting for humanity's right to unhappiness. 
 Another of my favorite things about his books are the characters themselves. While we do meet a lot of interesting people in this book, it was difficult to get a handle on many of them until nearly the end of the book. Some of the characters, while I got a shallow idea of them, I still don't really feel I know in a meaningful way, like Ophelia. Perhaps because we got a fairly clear view of many characters' backgrounds (Keats, Plath, Bug Man, etc.), I wanted to know the others that way as well. Perhaps that's coming in a later book. 
 The narration of this book is another strong point, and I was particularly impressed by the way Grant juggled between macro and micro viewpoints. It was always clear what was going on without ever having to be explained. Same goes for the science involved: I didn't really care where it came from or how it worked as much as how it played out in practice, and that's where the focus was. We didn't get a lot of dry, scientific mumbojumbo; the focus remained on the story. 
 One thing that keeps freaking me out, though, is wondering how plausible any of this would be. I doubt Grant has access to any top secret documents, and yet, I also know nanotechnology is real and there's just no telling who is using it and what for. But I'm just being silly....right? 
 Okay, just to be safe, I'm going to go microwave my clothes, and possibly my head.
