Maya Raines is an agent with New Zealand's Section One.
Section One is an ultra-secret member of that country's intelligence community and is charged with numerous duties but chief of them is the removal of enemies of the country that cannot be gotten rid of through legal channels. Wet works if needed. It was described in the narrative as "a black-ops programme that combined civilian intelligence gathering with paramilitary direct action. It allowed small teams of covert operators to find, fix and finish threats anywhere, everywhere". Additionally, "for all intents and purposes, Section One was a revolution. One that hit fast and hard, neutralizing persons of interest, disrupting terror networks. And it laid the groundwork for a new intervention policy - why publicly commit thousands of troops for kinetic action when you can just send in a handful of quiet professionals? Easy in. Easy out. Seamless".
At least it was until an op went very wrong in Kuala Lumpur and a key agent named Nathan Raines died. Then the same politicians who had eagerly created it went about gutting it. Now it is run by Deirdre Raines, former agent herself and widow of the slain agent. She is a woman who holds the appellation of Ice Queen, has earned that nickname many times over, and who would appreciate knowing she owned it but who would have been very unpleasant to the one letting her know.
Maya Raines is one of the top members of Section One. Her last name places her connection to Section One rather obviously but she is not an operative because Papa had been one nor because Mama is the head of the organization. She is one of the best because the same drive and innate abilities that coursed through their blood does through hers as well. In every form of armed combat, guns or knives or other, she is dangerous. With hand-to-hand combat she is positively lethal. She doesn't just know how to fight - she knows how to make sure she wins.
