Her glitch destroyed their system... or so she thought. It's been six months since Kaya, Bailen, and the Ghosts leveraged her glitch to destroy the tracker network. With it came the eradication of the authorities and an end to Rufus Scurry's secret plans to mind control the world. While Kaya appreciates her recovered sense of privacy and newfound connection to Judaism, millions believe life is worse without trackers. As the Ghosts deploy old technology to fill the void, people around Kaya begin acting strangely-doing things they don't have control over. Some, like her ex-boyfriend Harlow, are losing time all together. When Kaya receives a threat from an unknown user on her deactivated tracker, she seeks to uncover who is behind it and how they are using the old network. But more people are falling victim to the mind control every day, sending Kaya scrambling to end the loophole before she loses everyone she loves to the technology she's learned to live without.
