Verity, an out of work IT professional, interviews for a job at a somewhat mysterious Silicon Valley startup. After she takes the job, they issue her with a phone, a pair of augmented reality glasses, and earbuds. Once she tries them, it appears she is talking to an advanced emergent AI called Eunice, which the company has discovered and want to develop. Pretty soon, things go off the rails as Eunice explores her independence, brining Verity along for the ride. Meanwhile, from a future London of a parallel universe, independent operators contact Verity. They need to use Eunice in order to prevent a looming nuclear war in Verity’s timeline.
The concepts in this novel are complicated, and the reader must pay close attention, especially in the first third. The prose, as usual for Gibson, is terse and razor-sharp, and while it is masterful, it sometimes feels rather too constrained. The way in which Eunice develops her agency and independence, despite the efforts to stop her, is an interesting take on emergent AI.
