In Mirror City, a future metropolis where memories can be precisely erased, Ling Su is a top memory cleaner who makes a living removing other people’s pain. Yet he is haunted by fragmented visions that keep appearing in his own mind. A job that breaks the rules draws him into a vortex: the mysterious Su Wan doesn’t want to forget. She wants to recover a memory that was “erased.” When Ling Su delves into the depths of Su Wan’s disordered memories, he discovers that her past overlaps with his own visions. Beneath Mirror City’s dazzling surface lies a vast conspiracy to rewrite people’s lives, and Ling Su himself may be the most important prisoner in this labyrinth of memories.
