The Personal Librarian by Marie Benedict and Victoria Christopher Murray (Berkley, 2021)
This new novel is a collaboration between two authors brought together by their agents during the pandemic. It’s historical fiction that is based on the real life of the personal librarian to early 20th century industrialist J.P. Morgan. Belle DaCosta Greene came from African American roots but at her mother’s insistence changed her name and her identity to pretend to be white. Apparently she was light-skinned enough to get away with it but keeping the secret caused her unbelievable amounts of stress. She even had an abortion because a dark skinned baby would give her secret away. She did achieve her goal of success in her career as a librarian, although her role was more like a rare book collector. It’s a fascinating but disturbing story.
