When everyone has a brain-interfacing tracking chip, one glitch threatens the entire network. Kaya Weiss is that glitch.
Through thoughts and blinks, Kaya can access anyone or anything on the tracker network. But the authorities monitor everything-where Kaya goes, who she talks to, and what she searches. And without the ability to turn it off, Kaya and her family can't observe a tech-free Shabbat. To fix the glitch, the authorities slice into her skull to reset her tracker, leaving Kaya to question more than the system's invasion into her faith.
Kaya won't be a lab rat again.
Evading the authorities requires some serious tech skills the rogue underground Ghosts can offer. But Kaya's not sure she can trust them-even if their top tech wiz, Bailen, has interest in her running deeper than her bum tracker. Kaya must decide if gaining freedom is worth losing her tracker's infinite knowledge-because to take down the tracker network, she must betray the only tech she's ever known.
