Pyramid Lake

DARPA's bad-boy genius, Trevor Lennox, has built the government a top-secret supercomputer that can read lies and hidden secrets right off your face. But Trevor has no problem lying to his bosses, or using his invention to help his seven-year-old daughter when she faces a serious problem in school.
After brilliant, beautiful Cassie Winnemucca is assigned to Trevor's project, he suspects she's his replacement. But a series of gruesome murders rocks their secret government laboratory, and soon Trevor finds himself fighting to protect everyone and everything he cares about.
Shadowy forces have their own hidden plans for his face-reading technology... and there is no one they won't kill for it.
