Frank's Independence Day by M. L. Buchman

Name: Frank Adams
Job: Head of U.S. Secret Service Presidential Protection Detail

Name: Beatrice Ann “Beat” Belfour
Job: U.S. Secret Service Agent: Specialist in African Security

Agent “Beat” Belfour comes under fire when a coup erupts in the West African country of Guinea-Bissau. A routine diplomatic assignment goes wrong, and the Ambassador’s life now is slipping through her fingers.

Frank Adams’ only weapons to save her are: the President’s strategic skills, the dedication of the U.S. Army Night Stalkers helicopter regiment, and a past history with “Beat” that changed his life and his heart.
