Valentina Moretti, daughter of New York's most feared mafia boss, thought she could escape her past by betraying the only man who ever truly loved her—Nikolai Volkov, the ruthless Bratva heir she handed over to the FBI. Now she's trapped aboard the Silver Empress cruise ship when a deadly hantavirus outbreak places the entire vessel under CDC Level 3 quarantine. Passengers are dying. The military has sealed the exits. And the only man with the power, connections, and cold-blooded determination to reach her is the very one she destroyed. Nikolai survived her betrayal. He lost everything—his empire, his brother, three years of his life. Now he's back, more powerful and dangerous than ever, and he has one goal: make Valentina pay. But when he boards that ship under a forged CDC identity, old flames ignite in the darkest of places. In the shadows of a dying cruise liner, enemies become lovers, and the line between vengeance and obsession blurs until it disappears entirely.
