In 1810, while still at Eton, Percy Bysshe Shelley published Zastrozzi, the first of his two early Gothic prose romances. He published the second, St. Irvyne; or, The Rosicrucian, a year later. These sensationalist novels present some of Shelley's earliest thoughts on irresponsible self-indulgence and violent revenge, and offer remarkable insight into an imagination that is strikingly modern. This new Broadview Literary Texts edition also brings together the fragmentary remains of Shelley's other prose fiction, including his chapbook, Wolfstein, and contemporary reviews both by Shelley and about his work.
