In the ending of 'Sharp Objects', Camille finally confronts the truth about her family's dark secrets. She discovers the extent of her mother's abuse and the twisted nature of her sister's death. It's a complex and somewhat disturbing conclusion that shows Camille starting to come to terms with her past and the damage it has caused her.
The story mainly follows a journalist who returns to her hometown to cover a series of mysterious and disturbing crimes. There's a lot of psychological exploration and family drama.
