Taut, tense, terrifying. Marcus Sedgwick writes of the monsters we create in literature and in our own minds in this reappraisal of Mary Shelley's Frankenstein. 'Do monsters always stay in the book where they were born? Are they content to live out their lives on paper, and never step foot into the real world?' The Villa Diodati, on the shore of Lake Geneva, 1816: the Year without Summer. As Byron, Polidori, and Mr and Mrs Shelley shelter from the unexpected weather, old ghost stories are read and new ghost stories imagined. Born by the twin brain of the Shelleys is Frankenstein, one of the most influential tales of horror of all time. In a remote mountain house, high in the French Alps, an author broods on Shelley's creation. Reality and perception merge, fuelled by poisoned thoughts. Men make monsters; but who really creates who? A book about reason, the imagination, and the creative act of reading and writing. Marcus Sedgwick's ghostly, menacing novel celebrates the legacy of Shelley's Frankenstein .
