Inventing Victoria by Tonya Bolden

From Bloomsbury Publishing:

As a young black woman in 1880s Savannah, Essie's dreams are very much at odds with her reality. Ashamed of her beginnings, but unwilling to accept the path currently available to her, Essie is trapped between the life she has and the life she wants.

Until she meets a lady named Dorcas Vashon, the richest and most cultured black woman she's ever encountered. When Dorcas makes Essie an offer she can't refuse, she becomes Victoria. Transformed by a fine wardrobe, a classic education, and the rules of etiquette, Victoria is soon welcomed in the upper echelons of black society in Washington, D. C. But when the life she desires is finally within her grasp, Victoria must decide how much of herself she is truly willing to surrender.
