The Devil's Bargain.

“When Sophia Reyes' younger brother crosses the most dangerous mafia family in Naples, she has no choice but to face Enzo Carbone, the ruthless heir to the Carbone empire. In exchange for her brother's life, Sophia strikes a dangerous deal: she'll pose as Enzo's fiancée to help him protect his family's fragile grip on power. Enzo is used to getting what he wants through charm or force but Sophia is unlike anyone he's ever met. Her fiery defiance and unshakable determination threaten to unravel his carefully constructed world. She's a pawn in his game, but the more he draws her into his darkness, the harder it becomes to let her go. As their arrangement spirals into something deeper, an old enemy resurfaces. Marcella Vargas, the cunning leader of a rival cartel, will stop at nothing to see Enzo and his empire burn and she knows exactly how to use Sophia to bring him to his knees. Caught between loyalty and love, deception and truth, Enzo and Sophia must decide how far they're willing to go to protect the people they care about. But in a world ruled by violence and betrayal, can love truly survive or will their bargain cost them everything? Some deals are made in blood. Others are sealed with a kiss.”
