With the country on the brink of war, security takes on new meaning for Secret Service agent Cameron Roberts, whose mistress turns out to be the president's daughter. First daughter Blair Powell and her "secret" Secret Service agent Cameron Roberts are set to get married - with her father's blessing. But being in the spotlight isn't the safest place to be in a country still reeling from 9/11 and with the domestic terrorists who tried to kill Blair still on the loose. Cameron is reluctant to relinquish control when Blair's life is at stake, but there are other dangers at home and abroad that the President needs her to investigate, including the whereabouts of her previous mistress, Valerie Ross.
