I’m often called a genius with a forensic mind. But I never thought marrying the woman I love would depend on solving a murder. Nikolai Kostrov knows the odds of being allowed to wed his curvy Mafia princess are stacked against him. Still, he’s ready to put emotion before logic—risking everything for the woman who owns his heart. But persuading the cold Capo dei Capi to hand his sister to the Bratva will take more than love—especially when Nikolai is suspected of killing the man the Mafia intended her to marry. Now he must uncover the truth before their future is destroyed—because in this world, love isn’t enough to survive. I’ve been scared of my brother all my life. And now I’m terrified to tell him I’ve fallen in love with his enemy. As the sister of the Capo dei Capi, Isabella Dinelli is expected to marry for power, not for love. But she longs for the freedom to choose—just as her brother once claimed for himself. Determined to fight for her heart, Isabella strikes a deal that drags her into the bloody shadows of the Mafia. But when she can’t go through with it, someone else does the unthinkable for her. Now Isabella must uncover a killer—before murderous secrets tear her and Nikolai apart forever.
