WARNING!!! -Explicit-For years after Livana lost her sight, she lived in the gilded cage of her family’s expectations—engaged to the man chosen for her, confined to the shadows while he managed the empire her mother left behind. But blindness didn’t make her powerless. She heard everything. The whispers in the other room. The treachery in her fiancé’s voice. The betrayal woven into every conversation with her cousin, all caught by the devices she secretly planted.She had a plan to escape—one she’d crafted meticulously. Until her sister proposed something far more dangerous.Involve the Blackwells.Their family’s most hated rivals. The ones Livana had been raised to despise. And the man her sister suggested? *Damon Blackwell.* The arrogant bastard who had tormented her since childhood. The same man she’d once—*against her better judgment*—ended up in bed with after being drugged and set up.The idea was reckless. Madness. But the thought of burning her engagement to Knox to the ground, of watching her father and stepmother’s fury as she tied herself to their enemy? Delicious.What she didn’t expect was Damon’s obsession.He was ruthless. Unhinged. Exactly what she should have anticipated from the heir to the Blackwell mafia. But Livana was no damsel. If he thought he could control her, he was wrong.She had her own games to play.And this time, she wouldn’t be the one losing.

Three years into Qin Yu's marriage, his wife and in-laws all hated him.
