In a library where books don’t just hold stories but breathe them, a young apprentice named Anya is tasked with caring for the “Whispers”—the tiny, fleeting thoughts, daydreams, and forgotten ideas that drift in through the windows like dust motes. When a strange, silent hush begins to fall, causing the Whispers to fade and the stories in the books to grow dull, Anya must journey to the deepest, quietest part of the library: the Chamber of Unwritten Words. With her companion, a small booklouse who glows with the light of unread passages, she seeks the source of the silence, a forgotten word that has lost its voice and threatens to erase all the stories yet to be told.
