Interrupt

In Silicon Valley, profoundly deaf 12-year-old Wayne Faulkner tries to call 911 when an intruder stuns his father in the back yard - and 40,000 phones suddenly go dead. Wayne's father, Andy, can't figure out what happened, and he ought to see it at once: he's a telecom engineer, after all. But the terrorist Interrupt is clever, and Interrupt doesn't mind murder... Andy, soon a prime suspect, must identify Interrupt before the next killing - for Interrupt has taken Wayne. But Interrupt may be anybody, even the beautiful lineworker, Nell Colson. Anybody at all. The terrorist's code name is Interrupt and he is intent on taking down the phone lines. He will not let anything stand in his way, especially the telecom engineer father of a deaf son who depends on the phone lines for everything. It will take all that the father knows to save his son and stop the ruthless modern day terrorist. Refusing to accept blame when he is held responsible for forty thousand Silicon Valley telephones going dead, AT&T employee Andy Faulkner finds himself facing a murder charge and the kidnapping of his deaf son, Wayne.
