Samantha Reid, the White House Deputy Director for Homeland Security, deals with national security threats on a daily basis. When a natural-gas pipeline explodes in America's heartland, she senses pending disaster and tries to convince reluctant officials to take action. After several more explosions, Samantha teams up with Tripp Adams, Vice President of GeoGlobal Oil & Gas, owner of the pipelines, to investigate. As they race to solve the mystery of the explosions and determine the motives of the shadowy group behind the havoc, Samantha and Tripp spend days . . . and nights . . . together, growing ever closer. Then Tripp is sent on a business trip to South America---and disappears. Now Samantha must deal with political intrigue at the highest levels, finesse international plots, and break all the White House rules as she races to find Tripp and stop the team of foreign agents before they carry out their final deadly scheme.
