From The Grey House, Book Two, Inside the Grey House:
Natalia gave a nervous but proud laugh. “I feel like royalty.”
Lilly was carefully massaging conditioner into Natalia’s hair. “Stay with Vincent long enough and you will be.”
Natalia pulled away to look back at Lilly. She frowned at her healer. “What do you mean?”
“You’re Vincent’s woman. After you learn the ways of his house, you’ll run it.”
Natalia frowned. “Sounds archaic.”
“You will be given everything you want.”
