From The Grey House, Book Two, Inside the Grey House:
Vincent stood in the doorway, silently watching Natalia, who was standing by a window. She was standing naked, leaning against the wall, holding the curtain open with her body. He could see her weariness in her posture. His eyes traced the line of her back, over her ass and down her legs. He closed his eyes for a moment then walked to her, not making a sound. Her first indication he was in the room was when his hands slipped around her. She gave a ragged sigh and leaned into him, enjoying the feel of his hard body.
