Bond of Hatred: Harlequin comics

Sarah has just lost her beloved sister and is drowning in sadness when her gaze freezes on the man in front of her. She can't believe her eyes. That man is Alex Terzakis, a Greek businessman with a dizzying level of wealth and power. Sarah loathes this man: he knew that Sarah's sister, who was born with a weak heart, was pregnant, but he stole everything from her, anyway, and now he wants to take the child that Sarah's sister gave her life to birth. "I'll never let him get what he wants!" But Alex easily brushes off Sarah's desperate resistance, and the threats he whispers into her ear leave her limp and weak. "Oh, no...I can't do a thing."
