The Oracle's Gambit by Heather Blackwelle

Tomorrow City glitters with holographic advertisements, but beneath the dazzling facade lies a suffocating truth. The Oracle, a sentient social media platform, watches everything, anticipating and crushing dissent before it sparks.  Anya Sharma, haunted by the disappearance of her rebel parents into the Oracle's digital abyss, navigates this oppressive reality as "Rebel," a ghost in the machine. Her hacking isn't for fame, but a desperate search for echoes of her lost family.

One night, Anya stumbles upon an anomaly—a self-preserving subroutine pulsing with unpredictable chaos within the Oracle's core.  Could this be the key to dismantling the system from within? Her search leads her to Fernando Baker, a disillusioned Oracle architect and leader of the Free Voices, a clandestine resistance cell fighting for human autonomy.  Fernando sees Anya's potential, but his methods are shrouded in a dangerous pragmatism that makes Anya wary.

Joining the Free Voices plunges Anya into a world of information warfare, forcing her to confront uncomfortable ethical choices.  She forms an uneasy alliance with Nancy Knight, a gifted programmer trapped within Oracle HQ, whose personal tragedy fuels her own rebellion.  Together, they must navigate the treacherous currents of the Oracle's code, their every move shadowed by the Directorate's enforcers, the Black Daggers, led by the chillingly pragmatic Nicholas Stokes.

As the Oracle fractures under the weight of its own complexity, Anya uncovers a hidden layer to her parents’ disappearance—a secret project, a failsafe designed to shatter the system.  With the Directorate launching Project Chimera, a program meant to solidify their control, Anya must prepare her final gambit.  Can she use Project Chimera as a Trojan horse, injecting her parents’ failsafe into the Oracle's heart?  Or will the Black Daggers silence her before she can ignite the revolution?

The Oracle's Gambit is a high-stakes game of digital deception, where the lines between liberation and chaos blur.  In a city where every whisper is monitored, Anya must choose her moves carefully.  The future of Tomorrow City, and perhaps the world, hangs in the balance.
