You know, ever since Peter's first chapter you knew this would happen. You knew he would get caught and the marines would be send to extract him, fruitless. I must admit I sorta looked up against these chapters, and when reading them they were even more gruesome than I imagined. I think you really did a good job on sketching the grim atmosphere: First at Peter's hopelessness and later and the fatal fight of the marines as the clash upon the undead hordes in Verrückt. Also, loved how the Verrückt trailer quotes and scenes were in it, like those trailers are filmed scenes from this book.
That Brothers.exe file did it for me, though. Upon reading it, knowing what just happened to Peter and Dempsey and knowing what will happen to them in the future....damn. You see, this book is written for zombie fans, folks who already know the story. Each and every chapter you knew to surprise me as a reader, keeping it so enjoyful and well-written and introducing so many new things. It is perfectly canon but yet a whole new story, if you get what I mean, and that is the magic of the Storybook. But these two chapters are gruesome, because we already know what will happen. And so it will for other readers.
