A request from the commander-in-chief forces Secret Service Agent Cameron Roberts to break her word to the woman she loves—a woman who just happens to be Blair Powell, the president's daughter. Cam places duty before love, despite knowing that this decision may destroy her tenuous new relationship with the first daughter. As the rift between the two women widens, more than one would-be-suitor is happy to offer Blair the company that Cam cannot. Amidst political intrigue, and escalating threat to Blair's safety, and the seemingly irreconcilable personal differences that force them ever further apart, Cam and Blair struggle to find their way back to one another.
