But Julian isn't ready to surrender his favorite addiction. He enforces a final, hidden clause: The Twelve-Hour Debt. Before the sun rises and the papers are filed, Elena must spend one final, explosive night in his bed. ​It was supposed to be a goodbye. But as secrets from Elena’s own past begin to surface and a deadly game of betrayal unfolds, she realizes that the monster she married might be the only one who can keep her alive. ​In a race against time, where every touch is a lie and every pleasure is a trap, Elena must decide: Is she running from a killer, or is she falling back in love with the man who ruined her? ​Twelve hours. One last pleasure. A lifetime of consequences.
