The Obsidian Agreement

She came to destroy him. He made her love him instead. When corporate investigator Davina Kier is blackmailed into infiltrating the Obsidian Collective—a shadowy organization of elite operatives who manipulate global markets—she has one goal: destroy the man who ordered her sister's death three years ago. But Caspian Holt, the Collective's ruthless second-in-command, is nothing like the monster she expected. He's devastatingly intelligent, dangerously attractive, and sees through her lies from the moment they meet. Instead of exposing her, Caspian makes her a counter-offer she can't refuse: pose as his fiancée to help him execute an internal coup, and he'll give her the vengeance she craves. But every stolen kiss, every whispered secret in the dark, blurs the line between deception and dangerous desire. As they navigate a lethal game of betrayals, billion-dollar deals, and an organization that kills without hesitation, Davina realizes the only thing more dangerous than her enemies is how much she's willing to sacrifice to keep Caspian. But when she discovers the devastating truth about her sister's death—and Caspian's role in it—their fragile trust shatters. Now, with the Collective closing in and their hearts on the line, they must decide: destroy each other, or burn the whole world down together.
