Studying to be a dance student didn't work out, so Rayne takes the only course open to her, being a mercenary for Lexington Tactical. So what if they were the ones who tried to kidnap her. The money is good and she gets to work with her favorite marines doing what she does best, killing bad people doing bad things. With terrorists setting bombs throughout the city, there seems to be no shortage of people needing their attention. Throw in Dr. Elizabeth Gault, who wants her for the good of science, a cute boy who wants the key to her heart, a T80 combat AI sharing space in her head, and Rayne has plenty to worry about.
