Blindsight (Peter Watts)

This is a deeply complex, challenging book that touches on topics that are important to me professionally: the blindsight of the title, for one thing, and also saccadic blindness, Cotard syndrome, and the nature and value of consciousness itself. It wraps this up in a first-contact novel like none other. The story starts when millions of tiny sensors drop into our atmosphere all over the world and immediately burn up, presumably after sending information to some alien ship. Humanity throws together several waves of manned and unmanned probes to try to reach the aliens and learn about them, hoping to open a dialogue at best, to defend ourselves at words. The story follows a ship containing a linguist with four different identities, a marine with neural connections to armies of mechanized grunts, a biologist whose normal senses have been replaced with a whole array of sensors, and a synthesist whose job is to translate what experts learn into terms ordinary folks can understand, under the command of a vampire. Seriously. It all makes sense. The aliens are more completely alien than anything I've ever seen before, and they apparently think of us the same way. The story doesn't have a happy ending, not only because of what aliens may do to us, but because of what we are doing to ourselves. I read this long ago and remember thinking that I need to read it again so I can get more out of it the second time, because it is so dense. Now seemed like the right time, as I want to read his next book, set in the same universe: Echopraxia.
