Touch the past or wash it away? Two sisters have a choice in this unforgettable short story of everyday magic and the power of memory by the Hugo and Nebula Award–winning author Ken Liu.

Gui is a professional cleaner at A Fresh Start, scrubbing away the unpleasant layers of memory that build up on the personal objects of his customers. Memory-blind himself, he can’t feel those wounds. Clara can, and she prefers them irretrievable. Until her sister, Beatrice, ultrasensitive to memory, raises one that could change Clara’s mind. For Gui, the past is gone. For Clara and Beatrice, deciding what to remember reaches to the heart of their shared history.
