Historic preservation specialist Liberty Carmichael loves her position at the Library of Congress, caring for America's oldest documents. So when she intercepts an inside threat by a radical group planning to steal part of Thomas Jefferson's original collection, she takes it to the highest authority--her father, the president. When he fails to take the threat seriously, she steals the books to keep them safe.

Undercover FBI agent Cole Harding is close to disbanding the group responsible for killing his father. Believing documents once owned by Thomas Jefferson hold clues to answering a two hundred year old question, the group's next target is the Library of Congress. However, he wasn't expecting the First Daughter to get caught in the middle.

Will Cole convince the president to trust his abilities? Can he keep Liberty safe without blowing his cover? Can either protect their hearts?
