When the young and beautiful Kira Castelmaine arrives in Washington, D.C., to serve her first term in Congress, she is swept off her feet by Valentin Ashford, a distinguished political consultant. But the relationship soon turns the political idealist's moral world upside down. Unaware that Valentin is actually an agent of Lucifer sent to help bring world destruction, Kira falls wildly in love. Named to a seat on the powerful House intelligence committee, Kira eventually holds the swing vote on authorizing a covert action against a country in the Middle East that has recently obtained nuclear weapons. This covert attack threatens to be countered with an apocalyptic response, and it could trigger a wider conflict that could seal disaster for the human race. Trapped between passion and the salvation of mankind, Kira and Valentin must find redemption in each other if they hope to thwart Lucifer's diabolic plot.
