Tamar Glass fled an abusive mother when she was eighteen, running away from home to find a better life elsewhere. She has lived in freedom from her mother, Ruth, for decades, until one night she wakes to find her now-elderly mother standing over her bed.

As Tamar takes in her mother, strange events start happening inside her home: the house is oppressively hot, lights flicker, and cupboards open and shut on their own. Whispers filter beneath her bedroom door. Tamar learns that Ruth has been kicked out of her assisted living home, and other facilities refuse to house her and endanger their own residents. Tamar has spent years suppressing her childhood trauma, but it comes rushing back with each strange event in her home. As Tamar copes with their disturbing past, which her mother stubbornly refuses to admit to, she can't shake the feeling that there's something worse than her mother lurking in the shadows.

Perfect for fans of The Haunting of Hill House, this terrifying novel unravels one dark strand at a time.
