1739. Eliza Lucas, sixteen, is left in charge of the family’s three plantations in South Carolina, while her father goes to build a military career. Meanwhile, conditions on the plantations heat up: unrest begins among the slaves, and Eliza’s family is on the verge of losing everything.
The girl learns how much France pays for indigo dye. She is convinced this is the key to saving the plantations from ruin, but she doesn’t find support even within her own family. Still, Eliza decides to act and makes a dangerous—by the standards of those times—deal with one of the slaves: if he teaches her the thousand-year secret of making indigo, she will teach the slaves to read in return.
Thus begins an astonishing story of a girl who created a dye that became popular around the world. A novel about love, about secret and dangerous friendship, about aspirations and sacrifices one must make on the way to a goal.
