Nevertheless their lives were so closely intertwined, their choices, dreams and tragedies so eerily similar, it seems impossible to consider one without the other.Both women became famous writers; fell in love with brilliant but impossible men; and were single mothers who had children out of wedlock; both lived in exile; fought for their position in society; and thought deeply about how we should live. And both women broke almost every rigid convention there was to break: Wollstonecraft chased pirates in Scandinavia. Shelley faced down bandits in Naples. Wollstonecraft sailed to Paris to witness the Revolution. Shelley eloped in a fishing boat with a married man. Wollstonecraft proclaimed that women’s liberty should matter to everyone.Not only did Wollstonecraft declare the rights of women, her work ignited Romanticism. She inspired Coleridge, Wordsworth and a whole new generation of writers, including her own daughter, who – with her young lover Percy Shelley – read Wollstonecraft’s work aloud by her graveside. At just nineteen years old and a new mother herself, Mary Shelley composed Frankenstein whilst travelling around Italy with Percy and roguish Lord Byron (who promptly fathered a child by Mary’s stepsister). It is a seminal novel, exploring the limitations of human nature and the power of invention at a time of great religious and scientific upheaval. Moreover, Mary Shelley would become the editor of her husband’s poetry after his early death – a feat of scholarship that did nothing less than establish his literary reputation.Romantic Outlaws brings together a pair of visionary women who should have shared a life, but who instead shared a powerful literary and feminist legacy. This is inventive, illuminating, involving biography at its best.
