Mason "Mace" Perry was a firebrand cop on the D.C. police force until she was kidnapped and framed for a crime. She lost everything: her badge, her career, her freedom--and spent two years in prison. Now she's back on the outside and focused on one mission: to be a cop once more. Her only shot to be a true blue again is to solve a major case on her own, and prove she has the right to wear the uniform. Even with her police chief sister on her side, she has to work in the shadows: a vindictive U.S. attorney is looking for any reason to send Mace back behind bars. Then Roy Kingman enters her life.

Roy is a young lawyer who aided the poor until he took a high-paying job at a law firm in Washington. Mace and Roy meet after he discovers the dead body of a female partner at the firm. As they investigate the death, they start uncovering surprising secrets.

Soon, what began as a fairly routine homicide takes a terrifying and unexpected turn . . . into something complex, diabolical, and possibly lethal.
