A startling reevaluation of Lady Byron's marriage and the untold story of her complex life as single mother and progressive force.

The center of public attention after her tumultuous marriage to Lord Byron, Annabella Milbanke transformed herself from a neglected wife into a figure of incredible resilience and social vision. After she and her infant child were cast out of their home, she was left to navigate the stifling and unsupportive social environment of Regency England. Far from a victim or an obstacle to Byron's work, however, Lady Byron was a rebel against the fashionable snobbery of her class, founding the first Infants School and Co-Operative School in England. A poet and talented mathematician, Lady Byron supported the education of her precocious daughter, Ada Lovelace, now recognized and lauded as a pioneer of computer science, and saved from death her "adoptive daughter" Medora Leigh, the child of Lord Byron's incest with his sister. Lady Byron was adored by the younger abolitionist Harriet Beecher Stowe and by many notable friends. Yet her complex relationships with her family, including the sister Byron loved, runs like a live wire through this skillfully told and groundbreaking biography of a remarkable woman who made a life for herself and became a leading light in her century.
