The Bureau of Gentle Interventions has closed forty-one cases. One remains. It has been open for a hundred and eighty-three years.
The First Fracture is the oldest wound in existence - born the night someone rewrote a story without asking permission. It has been guarding every other story ever since, holding everything too tightly, out of fear it learned the hard way and never forgot.
Ward has been waiting to sit with it for two hundred years. Not to fix it. Not to close it by force. Just to sit down, set a cup between them, and stay.
Five agents. One archivist who is not what he appears to be. The chipped blue cup that has been on the shelf since the beginning. And the question that runs underneath every case the Bureau has ever taken: Is staying enough?
The Keeper's Cup is the final book in The Fracture Agents series - a story about the people who remain in rooms for others, and what it costs, and what it gives, and why they keep coming back.
