When Nadia Voss takes a live-in nursing position with the reclusive and powerful Rowan Ashford, she expects long hours, a difficult patient, and very little else — what she doesn't expect is to open his bedside drawer on her first night and find a photograph of her dead mother. On the back, in handwriting she doesn't recognize, someone has written four words that will unravel everything: *I'm sorry I never told her.* Nadia has never met this man, her mother never mentioned his name, and yet here is proof that Rowan Ashford carried a secret about Sable Voss close enough to sleep beside — a secret he has never offered, and she has never known to ask for. Now Nadia must do the one thing no one in this house seems prepared for: stay, and keep looking. Because the photograph was only the beginning, and whatever her mother never told her, someone in this house has been waiting — perhaps dreading — the day she finally found out.
