Slant - Greg Bear - Bog

In the sixth decade of the 21st century, the world has been transformed. Nanotechnology has been perfected, giving humans the ability to change their environment and themselves on the cellular level. And the study of the mind has brought about a revolution in both human psychotherapy and artificial intelligence.
It''s a sane and perfect world. Almost.
A man called Jack Giffey is planning to break into the Omphalos, the most secure building in all of separatist Green Idaho. Rumor says that the Omphalos houses the not-quite-dead, the very wealthy deceased who are still alive, their brains connected directly into Thinkers, Artificial Intelligences that provide a virtual reality. Data is the great treasure of the new millennium, and Giffey plans to tap into the Omphalos datastream, to steal the knowledge gathered by the inhabitants of the Omphalos.
In the offices of Mind Design, Inc., the most advanced Artificial Intelligence in the world has had a unique experience. She has received a request for contact from a new AI, one she does not know and did not help to design. Jill has never met a stranger of her own kind before; is it an alien Thinker, or the offspring of some vast conspiracy?
