Some museums preserve objects. The Museum of Conceptual History preserves the things civilisation would rather misplace: abandoned intentions, inconvenient truths, mild regrets and ideas that proved too dangerous to remember properly. Edric Quill is an assistant archivist, a former scholar and a devoted believer in labels, ledgers and the quiet mercy of correct filing. His life is orderly, uneventful and almost entirely feather-free. Then a black feather appears on his desk. It is followed by a file that should not exist, a map whose directions read like a threat written by a librarian, and a raven who informs Edric that he has been chosen-probably by mistake. Beyond the Museum's oldest stairs lies Branch 0: a hidden archive where books bite, records whisper, apologies require specialist handling and forgotten truths are kept because the world could not carry them. But something is moving through the shelves, leaving gaps where stories, names and memories ought to be. To protect both the impossible Library and the very ordinary world above it, Edric must decide what an archivist is truly for. Is his duty to preserve the past exactly as it was-or to keep its sharpest truths alive without allowing them to wound again? Darkly comic, richly whimsical and quietly moving, The Library of Unkind Things is a fantasy about memory, bureaucracy, ravens, regret and the dangerous kindness of refusing to let a story disappear.
