Rumored to be ruthless and merciless, Mafia Don Enzo terrifies the Colombo family’s two heiresses into fleeing their arranged marriages. In their place, 18-year-old Matteo is forced to disguise himself as the bride—but Enzo soon discovers that his seemingly delicate new spouse is actually the mysterious leader of Obsidian, the underground faction waging war against him. A brilliant pharmacologist and Enzo’s most dangerous rival, Matteo is also the only person who can cure the deadly poison slowly consuming the Don’s life. When their opposing identities are finally exposed and guns are drawn, Enzo realizes the greatest power he ever surrendered was his own life—and he placed it directly in Matteo’s hands.
