''Jed Walker is right there in Reacher''s rear-view mirror.'' Lee Child

Jed Walker has 48 hours to save the world.

The countdown has begun ...

The world is under cyber attack. The secretive terror outfit, known as Zodiac, are preparing to unleash chaos. The options for the hackers are endless.

From massive data breaches, take-downs of critical infrastructure, and commandeering military hardware, nothing networked is safe. Knowing where they will strike is half the battle. The only thing certain is their intent to create a devastating global catastrophe.

The US President has the power to enact the Internet Freedom Act - the ''Kill Switch''. Turning off the Net will stop the attacks. But it''s not that simple. The US will plummet into pandemonium if electronic communications cease. The rest of the world will follow.

One man, ex-CIA operative Jed Walker, has 36 hours to stop the terrorists. But for Jed, Zodiac isn''t the only thing he has to worry about. To protect the future he must reconnect with a woman from his past. No matter which way he turns, he has tough choices to make. Not everyone will get out alive. For Walker the countdown starts now . . .
