In 2067, memory is no longer a private sanctuary. It is a programmable frequency.

After the disappearance of her grandfather, Lucas Vireaux, Patricia Ferme travels to his estate in the mountains of Asturias expecting to grieve in solitude. Instead, she uncovers artefacts of his final work: a chamber where sound, and ancestral memory have been drawn into dangerous relation.

Lucas was a composer, and a recluse who believed memory was both stored, and enacted through rhythm, kinship, and place. What he leaves behind is a manuscript shaped by grief, and an invention capable of opening consciousness to lives buried far beneath recorded history.

As Patricia is drawn into the world of Vala, a seer whose rituals reveal the earliest grammar of human belonging, she begins to understand the unsettling reasons why Lucas hid his work.

Spanning deep prehistory, a fractured future, That Which Remembers Us is a novel about the human refusal to let love become corrupted data.
