Lyon, 1683. Catrin Bowen can coax from a dye vat a violet no other workshop in France can match — but the guild forbids women to hold a master's licence, and her father's sudden death leaves her thirty days to marry, sell, or lose everything. A wealthy silk merchant offers salvation, with one strange condition. Behind it lies a locked townhouse, a hidden ledger, and a woman kept from the world. Two lives, one impossible fight.
