La ragazza della porta accanto

The depiction of their suffering feels so raw and unsettling. I'm curious whether this was based on real cases or entirely fictional choices.

The story builds gradually but then hits a brutal stretch that left me breathless. Was this intentional to mirror the characters' descent?

The contrast between normalcy and evil makes the story even more disturbing. I wonder if the author grew up in a similar environment or wanted to challenge that perception.
