Olesia Anderson is an agent with Blackrock Association.
Blackrock is a private intelligence-gathering, security-providing, bodyguarding, in-your-face-do-not-mess-with-us corporation. It is one of the most powerful gaining many lucrative assignments from all over the world. Government agencies love using it because of the wonderful plausible deniability. Multinational companies love using it because they can be the good guys or the bad guys or the "we aren't sure which but we'll take no chances".
Anderson is a woman in her late 20's who has been with the company since she graduated college and was for several years one of their rising stars, a "AA-rated" agent. After a couple of rather messy faiures, neither of which were really her fault but she was one literally holding the smoking gun, her star has dimmed a fair amount and the first recorded assignment shows it.
While not a little annoyed that she is not as highly regarded as she once was, Anderson has no real desire to find work elsewhere. Working for Blackrock and doing what she does is all she has known as an adult and, to be honest, all she wants to do. She loves the excitement, the danger, and the thrill of winning.
There is no serious relationship in Anderson's life. She has no steady love interest and no great urge to find one. She definitely appreciates the male sex and picks up an interesting specimen from time to time but never with any plan on more than one or two nights. The first such temporary companion is actually kicked out of bed when the bosses call with a new mission and he doesn't move fast enough. Anderson has very little patience.
She does have a great aim with weapons and a very good ability to hold her own when no firearm is around. She can handle locks, heights, depths, and being on her own when she has to be.
Despite what her bosses might think of her, she can and does get the job done.
