Alivia Morgan is an agent with NEST.
That is the New England Special Terrorist Division. We are told that NEST was one of nearly a dozen regional anti-terrorist task forces created years ago in the wake of 9/11 under the umbrella of Homeland Security, the headquarters for this department "sat tucked into a nondescript industrial building toward the backside of the UMass Boston campus, a stone's throw from the JFK Presidential Library". It is lead by Director Luis Huerta.
The best agent that NEST has, and the one that Huerta will go to first whenever she is available, is Morgan. A single woman, 34 years old when we first meet her, she hails from Vermont where her parents and her nephew still live. She left home immediately after graduating high school because the call to serve her country and do her part in its defense was so strong, nothing else could have come before.
After joining the military, she would spend the next fifteen years in the US Army, "as she progressed up the ranks, eventually through Army Ranger School and into Special Ops". It was in the last couple of years there that overtures of joining Homeland Security began to be made. When she finally agreed, it was decided returning to her native New England was her most desired choices, thus making her a part of NEST. She has been with that organization long enough to become that premiere operative.
Morgan described as a tall, beautiful woman; she inherited her Mediterranean bronze complexion and looks from her mother and her height and athleticism from her father. "She'd been complimented plenty by her fair share of men over the years, though eventually her beauty turned into an added layer of difficulty throughout her military career. She often found herself having to prove that she was more than a beautiful face and flawless curves, or having to downplay her looks to avoid the attention." Despite the frequent compliments about her looks, though, Morgan remembers how she was always the skinny tom-boyish looking girl through all her school years; having not "blossomed" into the woman she is now, "she still saw the awkward plain Jane girl with braces and glasses looking back at her from the mirror."
Morgan is quite capable of and frequently happy with working by herself if needed but she does enjoy a small cadre of interesting colleagues to help survive the adventures. Top of that list is fellow operative, JJ, her main love interest.
