The Personal Librarian is a fictionalized account of Belle de Costa Greene, the real life librarian of the wealthy and powerful Glided Age industrialist J.P. Morgan. Greene was in charged of curating Morgan's extensive collection of rare manuscripts books, and artworks for his newly built J. Pierpont Morgan Library in Manhattan. Her proximity to Morgan made her one of the most powerful people in New York's art and book world, but she carried a secret; she was a Black woman passing for white. In this historical fiction, Greene struggles to keep her secret tucked away as she moves across the top echelons of New York City society.
