For five years, Amara Akinlade believed her older sister Sofia died in a car accident.Until she sees her on live TV — in a red dress, smiling on the arm of Matteo Costello, the ruthless Don who controls Lagos' underworld.That same night, four men break into Amara's house. Matteo himself sits in her father's chair."Sofia stole twenty million dollars from me and ran last night. Your father owes me forty million for her debts. He promised me Sofia as payment. Now she's gone. So you will take her place."Amara is forced into a contract marriage. Tomorrow, she must pretend to be Sofia's sister — the perfect, obedient replacement bride — at Matteo's engagement party, while he hunts her real sister down.But her sister left a secret: A diary hidden in Amara's old room that says: "If you're reading this, don't trust Matteo. He didn't kill me, but he killed the man I loved. And Dad sold me to him first."Now Amara is trapped in Matteo's mansion with two enemies:1. Matteo, who is cold, possessive, and starts to look at her not like a replacement, but like something he wants to keep. 2. Sofia, who suddenly calls her and whispers: "Don't marry him, Amara. Run before you become me." Amara's core struggle: She must survive the Mafia, find her sister before Matteo does, and uncover why her father really sold both daughters — while fighting her own dangerous attraction to the man who caged her.When Matteo discovers Amara has been secretly helping Sofia escape the country, he must choose: Kill the only woman who ever made him feel human, or burn his own empire to save her.
