Having an obnoxious AI in your head will really cramp your style, daddy-o... Introvert Reed Rothwell is part of a subculture of art deco era enthusiasts, pushing back against bland mainstream society and its mandated technology. Stuck with an AI assistant in his head is bad enough, but when he's inflicted with a forced upgrade to a new beta version, named Mazarin, the navigator starts to take on feelings and opinions of his own. When rumors spread of beta navs turning on their pilots, Reed is determined not to become a victim. Mazarin hasn't become violent yet--the AI is sympathetic and understanding--but with beta participants coerced into slitting their own throats, it's only a matter of time before Reed is next. The AI megacorporation already has an unhealthy interest in Reed, and all the beta testers who have sought help for their navigators have disappeared. The swingin' cats of the deco scene have the means to illegally terminate Reed's AI. But Mazarin has never tried to harm Reed--he loves Reed. Grappling with ridding himself of intrusive technology, the morality of hurting his self-aware AI, and avoiding the attention of a company that wants to sweep Reed's existence under the rug might be too much for one hep cat to handle.
