When Big Brother moves to space, who watches the watchers?

Commander Selene Ward returned from space a hero—but the classified structure she witnessed in orbit has made her a target for elimination.

The official story of her mission is a lie. Within days of coming home, her crew is silenced, flight records vanish, and the space agency that trained her transforms her into their most wanted fugitive.

When former mission engineer Noah Vale contacts her with evidence of a massive cover-up, Selene realizes she's not paranoid—she's being hunted. The mysterious orbital array she discovered isn't just surveillance technology. It's Dark Horizon, a secret program using satellite networks to monitor and control every aspect of human life on Earth.

Now racing across the country with ruthless operatives closing in, Selene and Noah must expose the truth before the system goes fully operational. As their desperate flight pulls them together, they face an impossible choice: sacrifice their growing love to save humanity, or watch the world fall under the shadow of orbital tyranny.

With 72 hours until global activation, two people who trusted the system must become the resistance.

Time is running out. Privacy is dying. And somewhere above them, the satellites are watching.

Will love survive when the entire world becomes the battlefield?

Perfect for fans of James Rollins' Sigma Force series, Matthew Reilly's action thrillers, and anyone who loved the conspiracy elements of Dan Brown combined with the romantic tension of Sandra Brown's suspense novels.
