He was sent to kill her. He stole her instead. Mateo "El Lobo" Cortez is the most feared enforcer in the Latin American cartel world. When he walks into an opera house with a loaded gun and hears Isabella Vega sing, he makes a decision that will ignite a war: he takes her alive. Isabella is a world-class soprano who has spent her life sheltered behind the walls of her father's empire, believing him to be a legitimate businessman. Blindfolded and dragged into a jungle fortress, she is given one rule: sing for him. Only for him. But captivity reveals a truth far darker than her captor. As Isabella uncovers her father's monstrous crimes — human trafficking, murder, and the killing of her own mother — her hatred shifts. The enforcer who caged her becomes the only man who ever told her the truth. The jungle fortress becomes the only place she has ever been free. When her father sends an army to reclaim her, Isabella doesn't wait to be rescued. She picks up a gun. She draws the maps that will destroy his empire. And she stands beside the monster she chose. This is not a love story. This is a war song.
