So far this story reminds me of the movie The Boy. Margot is now an orphan after her family was killed in a tragic accident. A nice, rich family has chosen to adopt her. But there’s a catch. Margot must be the companion to their daughter who suddenly and mysteriously became sick several months ago to the point that she is catatonic. Margot agrees to be the companion, because what could go wrong? I’m very interested to see what does go wrong to make this thrilling!
