Until you're mine

The plot kept me guessing at every turn, but I was wondering how Samantha Hayes planned these surprises so seamlessly. Did she plant clues early on or surprise readers with a different direction entirely?

The psychological depth made me sympathize with their pain, but also made me uneasy about trusting anyone completely. What feelings did this book evoke for others?

The tension felt so tangible, almost like the house itself was a character. I wonder if the locale was based on a real place or purely fictional but inspired by certain environments.
