Eliza McKay is an Extractionist: an expert in the virtual reality space where people's minds are uploaded as digital personas. When rich or important people get stuck in the Swim for reasons that are sleazy, illegal, or merely unlucky?it's McKay's job to quietly extract them. And McKay's job just got a lot more dangerous. After McKay repels an attack on her Swim persona, hired thugs break into her house to try to hack her cybernetic implants directly. Meanwhile, the corporate executive she was hired to rescue from VR space is surprisingly reluctant to be extracted. Something is lurking in the Swim, and some very powerful people will stop at nothing to keep it secret.
