Instrument of the Devil

Dial T for Terrorist.
Kahlil Sharivar can destroy the electrical grid with only a few keystrokes on a smartphone. His target: Montana's Hungry Horse Dam. Who will be blamed? Seasonal employee Tawny Lindholm, a lovely widow he seduces. Once he places the incriminating device in Tawny's hands, her life spins out of control. Soon the feds are chasing her and her family is in peril. Can Tawny turn the instrument back on the devil who set her up? If not, the lights go out and she dies.
