A seductive, disorienting novel that manipulates the fragile line between dreams and reality, unfolding over a day and a night in the sweltering heat of Seoul’s summer, by South Korea’s leading contemporary writer It’s 28-year-old Ayami’s final day at her box-office job in Seoul’s only audio theater for the blind. The theater is shutting down and Ayami’s future is uncertain.

Her last shift completed, Ayami walks the streets of the city with her former boss late into the night, searching for a mutual friend who is missing. Their conversations take in art, love, food, and the inaccessible country to the north. The next day, Ayami acts as a guide for a detective novelist visiting from abroad. Almost immediately, in the heat of Seoul at the height of the summer, order gives way to chaos as the edges of reality start to fray. Ayami enters a world of increasingly tangled threads, and the past intrudes upon the present as overlapping realities repeat, collide, change, and reassert themselves.

Blisteringly original, Untold Night and Day upends the very structure of fiction and narrative storytelling and burns itself upon the soul of the reader. By one of the boldest and most innovative voices in contemporary Korean literature, and masterfully realized in English by Man Booker International Prize-winning translator Deborah Smith, Bae Suah’s hypnotic novel asks whether more than one version of ourselves can exist at once, demonstrating the malleable nature of reality as we know it.
