Preston and Child do it again. This book could easily have been dialed in. In so many ways it feels like it's setting things up for more to come, but our intrepid authors continue to give each outing their all. It's full of research, science fiction, murder, mystery, and naval action enough to satisfy just about anyone. As always, they take liberties with the science and with the Earth itself, but in enjoying the ride, I really didn't care.
