A Second Book, Better Than the First: The Ghost Brigades, by John Scalzi

(Author's Note: This review will contain major spoilers for Old Man's War, so if you are planning on reading that book and don't want to know about what happens in it beforehand, hold off on reading this review. Thanks. - SW)

Though I don't think I said it specifically in my previous review, the best thing I liked about Old Man's War was the universe that it created: a universe full of everything that I both hope for and fear about a science fiction future, based on some of the best modern science I've ever seen used in a sci-fi novel. The best thing about its sequel, The Ghost Brigades, is that it expands that universe in ways that are unexpected, brilliant, and totally in keeping with my expectations for how the universe and the technology it revolves around would advance.

In Old Man's War, we see everything through the eyes of John Perry, a seventy-five-year-old man recruited from Earth to be given a new life as a super-soldier out in a galaxy fraught with war. We see the technology and the aliens and the politics he is introduced to through his eyes, giving us as good an introduction to the way things are as he gets. He does receive a slightly broader perspective than his fellow soldiers, though, when he discovers the existence of the Ghost Brigades, another group of super-soldiers that are cloned from the DNA of volunteers for the CDF that die before they can enlist. Specifically, he meets a woman named Jane Sagan who was cloned from his wife's DNA, and from her he learns a little about what it is like to be born as a fully-grown adult human, with a head full of knowledge but no memories, and how being bred to do nothing but fight can give one a very different perspective on life.

In The Ghost Brigades, though it is told from the point of view of more than one person, we finally get a first-hand look into the mind and experiences of a Ghost Brigade soldier. The story starts with Jane Sagan discovering an alliance that has been made between three alien races--the Rraey (the aliens who attacked Coral in the previous book), the Eneshans, and the Obin--who are planning on making war against the Colonial Union with the help of a human defector, a scientist named Charles Boutin. Everyone had thought that he had committed suicide, but he had actually just murdered a clone of himself before fleeing. Unfortunately, in his haste, he left a copy of a brain-scan he had done on himself behind, so the CDF, with the help of the Ghost Brigades, decides to clone him again and see if they can transfer his brain patterns into the new body in order to find out why he had defected and what information he was planning on giving their enemies. Things don't exactly go as planned, though, so they end up instead with a Ghost Brigade soldier, who is given the name Jared Dirac, and then we get to see the process by which someone becomes a Ghost Brigade soldier the same way that we saw John Perry become a CDF soldier before the story jumps off into the deep waters of the plot.

Throughout this book, Scalzi addresses the use of computer-brain interfacing in a way that is both well-researched and well-balanced, and, as with his first book, he uses likely end-results of technology that we already have or are working towards as a jumping-off point for larger discussions about politics, culture, intelligence, self-awareness, autonomy, and even the meaning of consciousness itself. And yet, there is never anything preachy about the narrative. The brilliance of telling these stories from individual points of view, even when doing so through multiple character perspectives within a book, is that it allows you to get each person's private thoughts and opinions on the events and draw your own conclusions based on your own thoughts and experiences with the same ideas. I love books that make me think without telling me what to think, and few books have ever made me think quite as much as this one did.

It is also one of the first times I have ever seen the discussion of the separation of intelligence and consciousness so brilliantly illustrated. Without giving too much away (I hope), I will say that it is discovered over the course of this book that the Obin are an uplifted species: the Consu (the super-advanced aliens from the first book whose motives for warfare with all the other species in the galaxy are inscrutable and vaguely religious) gave them intelligence at some point in their past, possibly as some sort of experiment. What they didn't give them, though, was consciousness. They can think, and reason, and understand, and create and use technology as well as any sentient species in the galaxy, but they have no higher emotions; they cannot love, or hate, or fear, or grieve. They have no culture, no ambition, and no desires except one--as a species, they know they lack true consciousness, and will do anything they need to in order to find a way to obtain it for themselves.

The Obin are almost the perfect way of explaining the difference between humans and animals who exhibit levels of intelligence that are very similar to ours. We know now that there are many highly-intelligent species of animals, but what all humans have that animals lack is consciousness--the ability to feel emotions based on our understanding of our past, future, mortality, and awareness of the world around us. And by bringing both the Obin and the soldiers of the Ghost Brigade together in this story, Scalzi delves deep into the realm of philosophy and brings modern science along for the ride. And this is only the second book of a trilogy! I can't wait to see what he does with the last one. :)
