I sold myself to save my mother's life, but I never knew I married the devil who destroyed my family. When Eliana signed the cold-blooded marriage contract with Cassian Blackwood, she wasn't chasing love, she was after a revenge. Cassian is ruthless, powerful, and untouchable. But to the world, he's the genius who built an empire in artificial intelligence and security. However, Eliana sees him as the shadow behind the mysterious death of her father, and the cause of her family's fall from grace to grass. Living under his roof, Eliana walks on a dangerous line, pretending to be the perfect wife while secretly hunting for the truth. But the deeper she digs, the more she's pulled into Cassian's broken world, one that's filled with dark secrets, scars and enemies that'd kill her just to get to Cassian. She came to destroy him, but what happens when the devil starts falling for his prey? In a world where love doesn't exist, and loyalty is a weapon, Eliana must choose; whether to expose the truth and loose him forever or risk her life for the man who might not be her enemy afteral.
