New Arrival: Blindsight, by Peter Watts

Just in is Blindsight, the new novel by Peter Watts. In 2082, a series of bright probes surrounds the Earth, then disappear, with indications that they are connected to something in the far reaches of the solar system. A spacecraft crewed by a linguist with multiple-personality syndrome, a cyborg biologist, and a genetically-created vampire is sent to investigate.
