Go rogue. Go dark. Go hunting.

Shadowy cyberterror group, Viper Nine, hold the world to ransom. It’s a devastating global attack, with spy agencies and militaries all under their control.

Enter Sam Driver and her team. As operatives who don't officially exist, they're the only ones who can track the hackers down. But little do they suspect how sophisticated their targets are, or how terrifying their plans.

With society in chaos, Driver and her elite unit must walk a tightrope between hunting Viper Nine and flying under the radar of their own governments.

If they’re exposed, it’s treason.

But as the net closes on the mastermind behind the attacks, Driver questions the motives behind her team’s actions.

Because when it comes to protecting the world, can the ends ever justify the means? And could she herself be about to switch sides?

The second heart-pounding thriller in the Sam Driver series, Rebel Dark is perfect for fans of Lee Child and David Baldacci.
