Thoughts after reading. Very good book. Fascinating descriptions and concepts. The mystery of it all was very well played. Apparently the crew had an orgy on the ship after all was said and done... ok...
In the end it holds it's place as a sci-fi classic and should most certainly be made into a movie. I think audiences are sophisticated enough to make it a cult classic at the very least.
I'll consider the sequels in the future. For now I'm moving on to
The Neanderthal Parallax by
Robert J. Sawyer.
