There is no more dramatic scene in literary history than the stormy night by Lake Geneva when Byron, Claire Clairmont, Polidori and the Shelleys met to talk of horror and the unexplained. From that emerged Frankenstein, a monster who has haunted imaginations for two hundred years. Miranda Seymour illustrates the rich and unexplored life of Mary Shelley. Everything from her childhood to her tempestuous relationship with Percy Shelley; Seymour brings to life the brilliant mind that created Frankenstein through unexplored and intriguing sources. The Mary Shelley we meet here is a woman we can engage with and understand. Her world, so rich in its settings and its cast of characters, seems drawn from a novel. She, at its centre, is flawed, brave, generous, and impetuous, a woman whose dark and brilliant imagination gave us a myth which seems ever more potent in our own era.
