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. But 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 from both the private and public world of the nation's capital. Soon, what began as a fairly routine homicide takes a terrifying and unexpected turn into something complex, diabolical, and possibly lethal.
