When MI5 learns that a horrifying new weapon is in enemy hands, agent Andrew Harvey is called in to track it down before it reaches British soil.
But then a woman is found murdered by the roadside and it soon becomes clear that London is in the crosshairs. The clock is ticking. Andrew and his girlfriend, Sarah, also a secret service operative, have only one lead: a beautiful refugee, desperate not to lose her son. But is she desperate enough to betray everything she believes in? And will she do it in time to help them prevent a terrifying attack?
As Andrew and Sarah race to unravel a convoluted web of subterfuge and exploitation, they discover there is more at stake than even they knew. And somewhere, at the heart of it, lurks a faceless enemy, who is prepared to use everything—and everyone—at his disposal.
