Canadian author Watts (Starfish) explores the nature of consciousness in this stimulating hard SF novel, which combines riveting action with a fascinating alien environment. In the late 21st century, when something alien is discovered beyond the edge of the solar system, the spaceship Theseus sets out to make contact. Led by an enigmatic AI and a genetically engineered vampire, the crew includes a biologist who's more machine than human, a linguist with surgically induced multiple personality disorder, a professional soldier who's a pacifist, and Siri Keeton, a man with only half a brain. Keeton is virtually incapable of empathy, but he has a savant's ability to model and predict the actions of others without understanding them. Once the Theseus arrives at the gigantic and hideously dangerous alien artifact (which has tellingly self-named itself Rorschach), the crew must deal with beings who speak English fluently but who may, paradoxically, not even be sentient, at least as we understand the term. Watts puts a terrifying and original spin on the familiar alien contact story. (Oct.)\nCopyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved.

The landscapes of other planets have long been the source of fantasies and speculation, but in the last few decades we've finally been able to get a close-up view of the surfaces of alien worlds.

"Mr Hawking thinks that, rather than actively trying to communicate with extra-terrestrials, humans should do everything possible to avoid contact. He explained: "We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet." "
