Mary Wollstonecraft Shelley (1797-1851) will forever be known as the author of one of the all-time great Gothic novels, Frankenstein; or The Modern Prometheus (1818). In 1824, she published her essay "On Ghosts", which offers a personal glimpse into her own opinions and experiences. This edition includes a new preface with historical context and an excerpt from M.G. Lewis' 1796 work The Monk: A Romance that Shelley references in "On Ghosts".
