From The Grey House, Book Two, Inside the Grey House:
Charlie covered his face with his hands. Part of him really wanted to stay and watch and witness whatever it was Natalia was plotting. The other, larger part wanted to pull her out of this apartment, get to the car and drive like the devil was chasing them all the way back to Vincent’s. When he pulled his hands away from his face, he gasped in surprise. She was standing right in front of him, reaching out to him. Her hand felt warm and soft on his cheek. He was astonished to find out he had to look up to look into her eyes, and when he did, the very familiar look in her eyes made him shudder in need.
