Before We Vanished

In 2038, Nguyen An sits before the ECHO machine in an abandoned Morrow building and sends her neural state back to June 1, 2025. For thirteen years, the conviction that she killed Khai has consumed her life, and she returns to prevent his death. Waking beside Khai, still breathing, she has seventeen days before the day he dies. But messages from an unknown number keep reminding her that last time she told him everything, and Khai died four days early. The more she pieces together her memories, the more she realizes she may be joining them with guesswork. The room where she remembers him dying was built only after the seventeenth. If memory can be planted, who wrote those thirteen years?
