Longlisted for the Carnegie Medal 1814: Two 16-year-old stepsisters run away with a married man. The results are devastating and the ripples will be felt for centuries. This is the incredible story of Mary Shelley - radical, rebellious and entranced. It is the story of a young woman who defies tradition and society, and who draws upon the monstrous elements of her own life to create the most memorable monster of them all. Acclaimed writer Sharon Dogar brings to life the passion, tragedy and forbidden love of Frankenstein's teenage author.
