When my twin brother Jayce orders a hit on Arabella Wilson—the daughter of our family’s greatest rival—I have no choice but to obey. Or so I let him think. But Arabella isn’t just the enemy … she’s also the only woman I’ve ever loved. Unfortunately, the longer I delay in carrying out Jayce’s orders, the more erratic he becomes. And then he issues the one ultimatum I can’t ignore: either I kill Arabella or he kills me. Since that isn’t how my story ends, I have a choice to make. Who lives, and who dies? Will it be my brother or my lover … my darkness or my light?
