In this haunting novel set in the magical hours between midnight and dawn, After Dark takes readers on a surreal journey through the streets of Tokyo. Nineteen-year-old Mari spends her night in a quiet Denny's, where she meets a young man who claims to know her older sister, Eri. This encounter sets off an odyssey through the sleeping city.

As the night unfolds, Mari becomes entangled in the lives of various city residents models, prostitutes, mobsters, and musicians whose paths intersect in unexpected ways. Meanwhile, her sister Eri remains in a deep, unnaturally perfect sleep that has lasted for months. Strange occurrences blur the line between reality and fantasy, drawing Mari deeper into a world that seems both ordinary and utterly fantastical.

Filled with Murakami's trademark humor and psychological depth, After Dark is an evocative exploration of time, memory, and the mysterious world of the night.
