Medal of Honor recipient Dan Lenson has just been assigned to the White House military staff—a dubious honor, serving a president the Joint Chiefs hate more than any other in modern history. His new concern is counternarcotics, and soon Lenson uncovers a troubling plot that involves a ruthless drug cartel, an assault on a nuclear power plant in Mexico, Islamic terrorists, and a devastating weapon aimed at the heart of America.

If saving the fate of a nation isn't enough, Lenson also suspects his wife is having an affair…with the Commander in Chief. As his marriage deteriorates and his frustration with Washington builds, Lenson becomes an unwitting accomplice in a dangerous and subversive conspiracy - to assassinate the president.

Now Lenson must operate at the highest levels of command to serve and protect the man he despises the most…and fight for the country, and woman, he loves.
