Sharp Objects

A book I read that just had the biggest plot twist. Basically a child if thirteen years addicted to attention. Of she didn't have the attention she would get rid of whoever was stealing her spotlight. Strangling girls her age and pulling out their teeth. How could a thirteen year old be that psychotic. And her mother loving to give attention. Purposely sickening her children to comfort them. Even going so extreme where her daughter had died because of her. And her sister who came from a big city back to her home town to solve a murder commuted by her own little sister. And craving to cut and self harm. Write words along her body for comfort and attempting suicide many times.
