This was the first of four books Hunter wrote for the Bantam publishing company. This was also the first of Hunter’s books made into Audio. From the hardcover dust jacket:
The countdown to midnight begins on a winter dawn. Doors burst open in the Hummel family home in suburban Maryland and commandos brandishing Uzi submachine guns rush inside. As his wife and children watch in horror, Jack Hummel, the local welder, is whisked away.The reason for Hummel’s abduction soon becomes clear: A sophisticated paramilitary assault team has taken control of the nearby South Mountain MX missile site. But the launch key rests within a vault behind a half-ton titanium block. Hummel must utilize his expertise to cut through the block to the key. By midnight South MOuntain will be fully operational – and the nuclear missile will be armed and ready to wreak destruction.
Where? And why? Who are these men who want to turn that key? Above all, who is the mastermind who has mounted such a staggering takeover of America’s most secret missile site?
