Is there something wrong with Ginette Cox? It’s what everyone seems to think. When a doctor suggests that what she might need is less excitement, she packs up and moves from New York City to a house in suburban NY: 19 Howard Ave. The town offers Ginette little in the way of entertainment in 1959, but at least she has interesting neighbors. Whether it’s the little girl with her doll or the couple and their mother-in-law, Ginette watches them from her window and makes up names and stories for them.

In 1919, Kitty Weekes, pretty, resourceful, and on the run, falsifies her background to obtain a nursing position at Portis House, a remote hospital for soldiers left shell-shocked by the horrors of the Great War. Hiding the shame of their mental instability in what was once a magnificent private estate, the patients suffer from nervous attacks and tormenting dreams.

Eleanor lives with prosopagnosia, the inability to recognize a familiar person's face. It causes stress. Acute anxiety. It can make you question what you think you know. When Eleanor walked in on the scene of her capriciously cruel grandmother, Vivianne’s, murder, she came face to face with the killer—a maddening expression that means nothing to someone like her. With each passing day, the horror of having come so close to a murderer—and not knowing if they’d be back—overtakes both her dreams and her waking moments, thwarting her perception of reality.

Jeremy works at the Video Hut in Nevada, Iowa. It's a small town in the center of the state - the first a in Nevada pronounced ay. This is the late 1990s, and even if the Hollywood Video in Ames poses an existential threat to Video Hut, there are still regular customers, a rush in the late afternoon. It's good enough for Jeremy: It's a job, quiet and predictable, and it gets him out of the house, where he lives with his dad and where they both try to avoid missing Mom, who died six years ago in a car wreck.
