Some melodies are better left unheard.

In the shadows of Crow's Foot Orphanage, twelve-year-old Elara has always been an outsider. Her only possession is a tarnished music box that refuses to open-until the night it begins to hum a haunting, forbidden tune. When the lid finally clicks open, it doesn't just reveal a dancing ballerina; it reveals a map to a world of gears and ghosts.

To uncover the truth about the parents who abandoned her, Elara must follow the music into the heart of a centuries-old conspiracy. But in a city where secrets are currency, someone is willing to kill to keep the music box silent.
