A woman describes a series of encounters she has with various people in the ordinary course of her life: an ex she runs into by chance at a public forum, an Airbnb owner unsure how to interact with her guests, a stranger who seeks help comforting his elderly mother, a friend of her youth now hospitalized with terminal cancer. In each of these people, the woman finds a common need: the urge to talk about themselves and to have an audience to their experiences. The narrator orchestrates this chorus of voices for the most part as a passive listener, until one of them makes an extraordinary request, drawing her into an intense and transformative experience of her own.

When a woman unexpectedly loses her lifelong best friend and mentor, she finds herself burdened with the unwanted dog he has left behind. Her own battle against grief is intensified by the mute suffering of the dog, a huge Great Dane traumatized by the inexplicable disappearance of its master. While others worry that grief has made her a victim of magical thinking, the woman refuses to be separated from the dog except for brief periods of time. Isolated from the rest of the world and increasingly obsessed with the dog's care, she comes dangerously close to unraveling. But while troubles abound, rich and surprising rewards lie in store for both of them.
