The Day Before Midnight — Stephen Hunter

The countdown begins when welder Jack Hummel is abducted from his suburban Maryland home and whisked to the South Mountain MX missile site--a top-secret nuclear complex now taken over by paramilitary terrorists.

All that stands between the Uzi-armed commandos and the launch button is a half-ton titanium block. They want Jack Hummel to cut through it--so they can unleash a devastatingly brilliant plot that threatens global disaster.

Now a Delta Force veteran and a think-tank defense wizard must get inside South Mountain--by defeating their own super-security systems and a darkly ingenious enemy leader...

...while Jack Hummel's torch burns closer and closer to the launch key... while the clock ticks closer to midnight--and Armageddon.
