Describe what the book is about.?

The novella is divided into three sections that detail the strange consequences of a seemingly innocuous decision, that of becoming a vegetarian. The first part, "The Vegetarian", tells of what happens when the main character, Yeong-hye, gives up eating meat after having a gruesome nightmare about the brutality of the meat trade. Her decision does not go over well within her family and her father taunts her so much that she is driven to slash her wrists. The second part, "Mongolian Mark", focused on Yeong-hye's brother in law, who is obsessed with her and whose own marriage suffers because of this obsession. The final third of the book, "Flaming Trees", chronicles the descent into madness that follows from Yeong-hye's decision to become a vegetarian, and her decision to become a plant to avoid the brutality of humans is seen as an advanced case of mania.
