New Orleans Police Detective Rick Easterling is no saint. He's the NOPD's best undercover cop. Known as the Man of a Thousand Faces, he's a rogue–breaking rules to solve cases his way. But when his brother dies of a drug overdose and he’s suspected of being a dirty cop, Rick vows to clear his name and avenge his brother’s death.
Rookie police officer Lusinda Johnson has a personal axe to grind with dirty cops, so she volunteers to work undercover and shadow Rick. She tells herself she can remain immune to his sexy, brooding demeanor, but the longer they work together, the harder it is to see him as anything other than a hero.
As “Sin” and Rick investigate the corrupt underbelly of New Orleans night life, the lies they must tell each other imperil them almost as much as the drug lords closing in. Will they learn to trust each other in time to save themselves and explore their growing love?
