True Colours of the Chameleon - Manda Benson

"My old boss made sure to burn my bridges when I lost my job. I'm a fallen synthetic chemist no pharmaceutical company will employ. However, it turns out there are other places my skills are in demand, and they don't ask for references."

Although originally recruited into a rising criminal gang to design illicit drugs for the black market, 'Doc' finds herself becoming embroiled in the gang's activities and drawn towards forgery expert and master of disguises, 'Cam'. When a heist of the Blue Moon Casino goes wrong, Doc and Cam find themselves on the run with the spoils, pursued not only by the police, but by fellow gang members who want the money for themselves and the pair dead as witnesses. As enemies close in, Doc finds herself pushed to her limits, her grasp on right and wrong slipping when she is called upon to defend herself and Cam, and it becomes apparent Cam is holding back secrets about his past that threaten to shatter her trust in him.
