Brooke Grant is an agent for the President.
When we first meet her she is a captain in the U.S. Marine Corps serving as military attache at the newly reopened embassy in Mogadishu, certainly not the most glamorous, or safe, duty assignments.
29 years old, single and attractive. That last would have usually explained why she, through no desire on her part, was often "shown off at diplomatic affairs" instead of being put on "more meaty assignments" but in her case sexism gave way to the fact that her uncle was the current chairman of the Joint Chiefs of Staff and someone known for being very protective of her. This constantly irked the very determined and capable Grant who would prefer to be asked for harder assignments. She would definitely get what she desired.
We learn also early on that the reason for the high-ranking uncle's devotion is because he had years before stepped in to care for the then teenaged Grant when her parents died in the Towers on 9/11. Grant for her part adores her curmudedy uncle but chafes under his protectivism. This will likely aid in her taking the extremely dangerous tasks offered her.
The three adventures that exist concerning Grant are more than her exploits, though her actions are critical in each one. They are also political thrillers with a considerable amount of activity taking place in government offices, especially the Oval Office where the sitting female President Allworth is constantly being challenged by circumstances to pull off a miracle. What brings the tales back around to Grant, an African-American officer who prefers to stay out of the limelight but who finds that difficult when her actions turn out to be so important.
The trilogy is also the story of an enemy of America calling himself the Falcon, a very mysterious and utterly ruthless Islamic extremist terror leader whose audacious scheme in the first recorded adventure is foiled by a quick thinking and very determined Grant and who then issues a fatwa against her
