By Nightfall

Peter and Rebecca Harris, a seemingly content middle-aged couple, navigate their comfortable yet increasingly predictable lives in New York's art world. Peter, an art dealer grappling with his own artistic failures and the encroaching ennui of middle age, finds his carefully constructed world irrevocably altered by the arrival of Rebecca's younger brother, Mizzy. A magnetic, enigmatic aspiring artist, Mizzy bears an unsettling resemblance to Peter's idealized younger self, triggering a profound crisis of identity, desire, and regret within him. As Peter becomes increasingly infatuated with Mizzy, mistaking the younger man for a vessel of his own lost youth and unfulfilled potential, the novel delves into the intoxicating power of perceived identity and the poignant realities of aging, artistic integrity, and marital fidelity. Cunningham masterfully explores the complex interplay of love, longing, and self-deception that threatens to unravel the very fabric of the Harrises' marriage and their understanding of themselves.
