idoru

Idoru is the second book in William Gibson's Bridge trilogy. Idoru is a science-fiction novel set in a postmodern, dystopian, cyberpunk future. One of the main characters, Colin Laney, has a talent for identifying nodal points, analogous to Gibson's own:

Laney’s node-spotter function is some sort of metaphor for whatever it is that I actually do. There are bits of the literal future right here, right now, if you know how to look for them. Although I can’t tell you how; it’s a non-rational process.
