When the National Security Agency was caught wiretapping U.S. citizens without warrants, a political scandal erupted and the secret program came to a screeching halt. But the senior man at the NSA who spearheaded the most sophisticated eavesdropping operation in history wasn't about to sit by while spineless politicians sleepwalked his country into another 9/11. Instead, he moved the program into the shadows. But being in the shadows can cause complications.

When the NSA illegally records a rogue military group murdering two American civilians, they can't exactly walk over to the Pentagon and demand to know what's going on. That doesn't mean the NSA's hands are tied, however. As the largest intelligence service in the country, both in money and manpower, they have plenty of options - mostly illegitimate.

DeMarco learns all too well just what the NSA is capable of. They bug him, threaten him, and use him to draw out their opponent. But DeMarco doesn't like being used. A strong addition to this celebrated series, House Divided continues Mike Lawson's impressive run of inspired, compelling thrillers.
