The White House National Security Series

The revised story of Checkmate is the first in The White House National Security series and features young scientist Dr. Cameron Talbot who invents a breakthrough technology to defend against cruise missiles. She needs support from skeptical company officers, funding from a reluctant Congress, and help from Lt. Col. Hunt Daniels, detailed to The White House NSC. With disaster brewing overseas, threats to New Delhi, the Taj Mahal, and to Cameron herself, she and Hunt find themselves enmeshed in terrorist plots and political wrangling at the highest levels. 

In this second book of the White House national security thriller series, Dr. Cameron Talbot, a famous expert on missile defense systems, returns to investigate how American airplanes could plummet from the sky - though nothing shows up on radar and none of the usual terrorist suspects have claimed responsibility. With the country in a panic and the economy taking a nose-dive, the beautiful scientist finds herself once again enmeshed in international plots as well as a romantic triangle in the highest levels of government.
