Under 365nm light, a black mourning ribbon speaks. Maya Desrosiers, a textile conservator in Philadelphia, uncovers a secret stitched in iron‑gall ink: the first‑person testimony of Dinah, a enslaved seamstress who carried messages and named a betrayal at the birth of a nation. As America's 250th anniversary builds a curated story of unity, museum sponsors urge silence and context‑control. Maya must choose between conserving a fabric and conserving a truth. Between family protection and public reckoning. Between career and the woman who was never heard. A sharp, sensory mystery of fibres and power, Unstitching Liberty follows a quiet fight over who owns history—and what it costs to let a hidden voice be known.
