An Ordinary Violence

Dawn has come home to her father's after breaking up with her boyfriend, and stabbing him with a pencil. And quitting her job. I loved her right away. Also coming home is her brother Cody, he is being let out of jail.
Dawn's unlikeable- and I do love an unlikeable main character. She can only hold herself together for small chunks of time, she's super judge-y, and she's unkind to her father.
Then things get weird. I want to say it is folk horror adjacent? Cody and his new BFF are up to something supernatural and Dawn's (deceased) mother starts speaking to her via the living but only a few words at a time.
A fever dream of a novel.
I really enjoyed it.
