For Cathy, life as she’s always known it seems to be slipping away. Her sense of significance is crumbling as she worries that her husband is having an affair and her thirteen-year-old daughter is becoming estranged. Desperate to regain some semblance of order, Cathy retreats to her sister’s home, where she cat sits, compulsively cleans, and spies on a neighboring family.

Yet when Cathy becomes the object of the teenage son’s obsession, he threatens to unravel everything—from her precarious marriage to her daughter’s innocence to her own wavering sanity.
