I started listening to an audio book but I somehow can't find it on YouTube anymore and I cant remember the title.
It was about a woman who had a sister with Down syndrome and a very very controlling husband who basically kept her prisoner in her own home but very subtly so most of her friends thought they were a perfectly normal couple. He was threatening her with doing something to her sister if she ran away/told anyone. The sister was due to come to live with them after she finished at a residential school.
Anyone have any ideas?
