Giuliana spent four years supporting her boyfriend Marco through architecture school, working double shifts while he pursued his dreams—until graduation day, when she discovered the Tiffany bracelet he gave her was engraved with someone else's initial. Abandoned at the train station and betrayed by both her boyfriend and best friend, she makes a call to the one person who can give her the power she needs: her estranged mafia don father. Within hours, she's offered a deal—a strategic marriage to Dante Salvatore, heir to Europe's most prestigious architectural firm, in exchange for destroying Marco's career before it begins. But when anonymous texts reveal that Marco's affair has been going on for eight months and that her future husband personally recommended Marco for his dream internship that very morning, Giuliana realizes her revenge is already unraveling. Now she must decide whether to trust the dangerously perceptive man she's agreed to marry, or handle her betrayal the way a true mafia princess should—alone, ruthless, and without mercy.
