She was supposed to analyze the data. Not become the target.

NSA cryptanalyst Sara Kwon spends her nights chasing patterns in satellite chatter-ghosts hidden in static. But when one encrypted fragment spits out a single word, Dominion, she knows she's crossed into forbidden territory. The system shuts her out, someone traces her connection, and suddenly the hunter becomes the hunted.

Her trail leads to a mothballed military uplink in the Appalachian hills-a site brought back online by people who don't exist. Inside the chatter is a countdown to a catastrophic strike on U.S. soil. And buried deeper is a digital fingerprint from a legendary rogue hacker long believed gone.

With the clock ticking, Sara must vanish off-grid, outthink a shadow conspiracy, and sabotage the attack before it hits the nation's capital. Alone, outgunned, and under surveillance, she has only her skills, her instincts, and a desperate phone call to an agent named Emily Jensen.
