What is "gridlinked"

Gridlinked is Neal Asher's first novel, published by the Macmillan Publishers imprint Pan Books in 2001. It contains elements of the technological inventiveness of hard science-fiction with a more contemporary political plotline. The novel follows the exploits of Earth Central Security agent Ian Cormac, as he attempts to discover who or what is behind the destruction of the Runcible on a remote colony. Cormac drops an investigation into Polity separatists on Cheyne III, and takes the starship Hubris to the ruined world of Samarkand to directly oversee the investigation there. Having been directly "gridlinked" to the Polity A.I. network for too long, Cormac has been slowly losing his humanity, and takes the opportunity of this particular mission to disconnect and solve the mystery the old-fashioned way.
