Camouflage by Joe Haldeman

Joe Haldeman wrote one of my most favorite books, The Forever War. This was one of the books that I borrowed from my Dad's stack of paperbacks when I was in Junior High or High School. He was a big science fiction fan, subscribing to Analog magazine in addition to reading lots of paperbacks. The Forever War was one of those books that really sticks in your mind.

When I saw the book Camouflage in the library, I picked it up without considering anything beyond the author's name. I started to read it and kept thinking that it was familiar. After the second chapter, I knew I had read it before, but it was vaguely different. I stopped worrying about the deja vu feeling and just enjoyed the reading.

The book is about two aliens that have been on earth for thousands of years. They were both shapeshifters. They could change their shape and appearance. The main character was followed from his background. Haldeman painted an image of a portion of a small cluster galaxy where the stars were close and orbits of planets were continuously disrupted. His speculation was that anything that survived and evolved in this environment would have to be supremely adaptable. They would have to be almost impervious to damage, able to survive on almost any kind of food, able to regenerate their bodies, and as such, immortal. In addition to all that, they would have to be able to go dormant for long periods of time. The main character had travelled through space for millenia and crashed into the earth a couple of million years ago. His ship was embedded under a volcanic flow on the bottom of the Pacific Ocean, and he had assumed the shape of a Great White Shark for most of that time. He emerged onto land right before WWII and took the shape of a man that he killed on the beach. While learning to be human, he acted very un-human. Eventually, he learned how to mimic human behavior and had some adventures, including being beheaded on the Baatan Death March.

While all this is going on, there is another shapeshifter who has been playing at being human much longer. He perpetually picks a bloodthirsty and powerful character to become, like a death camp guard in WWII. He suspects that there must be another being like him somewhere and sets out to find him so he can kill the competition.

The story comes to a strange climax, and I won't spoil it more than I already have. I liked the whole concept of how to sneak through society with the increasing use of fingerprints and retinal scans. It was also interesting how the main character had to follow to a certain extent the principle of conservation of mass. To be something bigger than he was, he had to absorb mass. To be something smaller, he had to shed mass.

Where did his consciousness reside? How do you retain memories over such a long period of time? These were questions that were not answered by the novel, but the fact that I am questioning the novel as if it was an actual account tells you something about the completeness of the worlds Joe Haldeman creates.
