Hired by J.P. Morgan to curate a collection of rare manuscripts, books, and artwork for his newly built Pierpont Morgan Library, Belle da Costa Greene becomes one of the most powerful women in New York despite the dangerous secret she keeps. In her twenties, Belle da Costa Greene is hired by J. Pierpont Morgan to curate a collection of rare manuscripts, books, and artwork for his newly built Morgan Library. Belle becomes a fixture on the New York society scene and one of the most powerful people in the art and book world, known for her impeccable taste and shrewd negotiating for critical works as she helps build a world-class collection. But Belle has a secret: she was born Belle Marion Greener, daughter of Richard Greener, the first Black graduate of Harvard and well-known advocate for equality. Belle's alleged Portuguese heritage lets her pass as white, but she will go through great lengths to preserve her carefully crafted identity in a racist world. -- adapted from jacket
