A princess, tormented by the prison of her own mind, seeks out Nestor, the magician of memories, begging him to mend what's broken so as to be whole again. For a fleeting moment, she tastes the sweetness of life she always dreamed of, until the dream curdles and she collapses into a nostalgia far crueler than the pain she tried to escape.

In a frost-bitten metropolis where machines outlast their makers, Investigator Esfir Khairova is drawn into a string of gruesome murders known as the Sweet Tooth killings. Each crime feels disturbingly familiar, as if she’s trying to find a part of herself in the killer's mysterious motivations. The deeper she delves into the case, the more she senses something fractured within herself, a dissonance between what she remembers and what she is.
