A very disappointing sequel to Gibson's terrific "The Peripheral" (2014). The primary problem (there are others) is that the dramatic structure falls apart midway through, and the remainder of the novel unfolds in almost deus ex machina (in this case deus ex AI) fashion. The anti-climactic conclusion, which wraps up far too neatly and antiseptically, is so boring that I found myself skimming whole pages near the end. I probably wouldn't be quite so negative if I hadn't keenly anticipated this sequel. Still, I wish I hadn't wasted my time reading this.
