It is the twenty-first century, and England is a republic governed by a ruling elite, one of whom, Adrian, Earl of Windsor, has introduced a Cumbrian boy to the circle. This outsider, Lionel Verney, narrates the story, a tale of complicated, tragic love, and of the gradual extermination of the human race by plague. The Last Man also functions as an intriguing roman a clef, for the saintly Adrian is a monument to Percy Bysshe Shelley, and his friend Lord Raymond is a portrait of Byron. The novel offers a vision of the future that expresses a reaction against Romanticism, as Shelley demonstrates the failure of the imagination and of art to redeem her doomed characters.
