"FBI rookie Evelyn Hart is betrayed by a mole during a covert operation and sold at an underground auction. Just as she is about to fall into the hands of a ruthless criminal, Seraphina Moreau—the powerful leader of the Obsidian Group—purchases her for twenty-two million dollars. To Evelyn’s shock, the cold and dangerous mafia queen is the same woman she loved and left behind seven years ago.
Believing that Evelyn revealed her mother’s location to the FBI and caused her death, Seraphina imprisons Evelyn in her castle, disguising her unresolved love beneath revenge, control, and possessiveness. But as the truth behind the FBI mole, the illegal auction, and the rival Silver Legion begins to surface, they discover that the betrayal seven years ago was part of a far greater conspiracy. Evelyn is not merely a helpless victim, either—she is an undercover agent operating under the code name Nightingale.
One is bound by her oath to the FBI; the other rules a powerful criminal family. Although they know they are hiding secrets and using each other, they fall in love again through betrayal, danger, and repeated brushes with death. With the final operation against the Family Council approaching, Evelyn and Seraphina must choose between justice, power, and love.
Will they destroy each other to complete their missions—or join forces to end a conspiracy that has haunted them for seven years?"
