The series began with Avery Keene as a Supreme Court law clerk in While Justice Sleeps. Now she’s working at a D.C. law firm, but that’s not fulfilling enough, so instead of working solely as a lawyer, she’s doing investigative work at the firm. It’s how she lands a whopper of an assignment: a new AI system is meant to change the medical system and industry, but there have been a lot of problems in the company—most concerning the death of an engineer. Avery gathers her most trusted people as the tech company tasks her to investigate them by identifying any and all problems so they can be fixed. With billions on the line and the very controversial AI at the center, what could go wrong?

Mae Pruett works as a fixer for celebrities and the über-rich. The firm she works for basically cleans up their messes, ranging from babysitting a once child star to get her shit together to helping truly vile and cruel people get away with anything. She’s good at her job and not concerned with the morals of it. That is, until her coworker tells her he has something important to tell her and then dies in a carjacking gone wrong. Mae isn’t satisfied with the police’s ruling and goes rogue, partnering up with her ex, Chris. He’s also not working from a place of high morals or the law, and works in private security. Once they start digging into the murder, their lives are put in danger, and they realize they are willing to risk everything to solve this case—all while being forced to question whether they are okay with the people they’ve become.

Mackenzie Clyde is a lawyer, but doesn’t work as one, as she informs a tech CEO in the opening of the book.

In the flashback chapters, you get to see how Mackenzie grew up and ended up in this line of work as a “fixer,” and in the present, you watch her fall down a rabbit hole of how Silicon Valley is run, all while placing herself in danger…
