A dedicated cop, an elusive criminal, and the man caught between the two... After tracking the notorious Selena for over a year, Detective Mia Gonzalez has hit a brick wall in her investigation. But when Mia discovers her striking resemblance to the criminal mastermind, she goes undercover in order to unravel their business from the inside. What she doesn't count on is falling for Donovan. Spending so much time with the dark, mysterious-and dangerous-man, Mia finds an entirely different side to Donovan's personality. Not only is he a cunning businessman, but he's also a thoughtful and caring partner to Selena. In order to survive, Mia must remember there's only one way to stay alive inside the viper's nest-she must become a viper herself. Selena is as mysterious as Donovan is enticing. She built her empire from the ground up, all while managing to stay out of the spotlight. Someone who works in the shadows always carries secrets, and Selena is no exception. ¿ When Mia makes a shocking discovery, she escapes Donovan's luring presence only to realize she has nowhere to go. Afraid to leave, terrified to return, Mia huddles in a dark, cold, underground tunnel while attempting to mend the pieces of her psyche. When she finally gathers the courage to face her demons, Mia is captured and held prisoner by the DeLuca family. With Donovan in their grasp, she's faced with a difficult decision-but for her, there's only one choice. Rescue Donovan, take down the DeLucas, and find a way to get herself out of the mess she created. ¿ These two worlds are about to clash in the ultimate battle between good and evil. Only one will survive. Only one will rise victorious.
