Introduction Mary Shelley states that in 1818 she discovered, in a cave near
Naples,
prophetic writings painted on leaves by the
Cumaean Sibyl. She says she has edited these writings into the narrative of a man living at the end of the 21st century, commencing in 2073 and concluding in 2100.
Volume 1 Lionel's father was a friend of the king before he was cast away because of his gambling. Lionel's father left to take his life, but before he did so he left a letter for the king to take care of his family after his death. After Lionel's father died, the letter was never delivered. Lionel and his sister grow up with no parental influence and become uncivilised. Lionel develops a hatred of the royal family, and Perdita grows to enjoy her isolation from society. When the king leaves the throne, the monarchy comes to an end, and a republic is created. When the king dies, the Countess attempts to raise their son, Adrian, to reclaim the throne. However, Adrian opposes his mother and refuses to take the throne. He moves to
Cumberland where Lionel, who bears a grudge against Adrian and his family for the neglect of the Verney family, intends to confront Adrian. He is mollified by Adrian's good nature and his explanation that he only recently discovered the letter. The two become close friends, and Lionel becomes civilised under Adrian's influence. Adrian assists Lionel in pursuing political endeavours in
Vienna, which Lionel accepts, and leaves for 2 years. He later chooses to return to England because he has not heard from either Adrian or his sister. Lionel returns to England to face the personal turmoil amongst his acquaintances. Lord Raymond, who came to be renowned for his exploits in a war between Greece and Turkey, has returned to England searching for a political position. Perdita and Evadne soon fall in love with him. On discovering that his beloved, Evadne, is in love with Raymond, Adrian goes into exile, presumably mad. Raymond intends to marry Idris (with whom Lionel is in love) as a first step towards becoming king, with the help of the Countess. However, he ultimately chooses his love for Perdita over his ambition, and the two marry. Under Lionel's care, Adrian recovers but remains physically weak. On learning of the love between Idris and Lionel, the Countess schemes to drug Idris, bring her to
Austria, and force her to make a politically motivated marriage. Idris discovers the plot and flees to Lionel, who marries her soon after. The Countess leaves for
Austria, resentful of her children and of Lionel. Adrian and the others live happily together until Raymond runs for Lord Protector and wins. Perdita adjusts to her newfound social position, while Raymond becomes well-beloved as an administrator. He discovers, however, that Evadne, after the political and financial ruin of her husband (on account of her own political schemes) lives in poverty in London, unwilling to plead for assistance. Raymond attempts to support Evadne by employing her artistic skills in secrecy, and later nursing her in illness, but Perdita learns of the relationship and suspects
infidelity. Her suspicions arouse Raymond's proud nature, and the two separate. Raymond resigns his position and leaves to rejoin the war in
Greece, accompanied by Adrian. Shortly after a wounded Adrian returns to England, rumours arise that Raymond has been killed. Perdita, loyal nonetheless, convinces Lionel to bring her and Clara to Greece to find him.
Volume 2 Arriving in
Athens, Lionel learns that Raymond had been captured by the
Ottomans, and negotiates his return to Greece. Shortly after this, Lionel and Raymond return to the Greek army and fight their way to
Constantinople. After a decisive battle near Constantinople's gates, Lionel discovers Evadne, who was wounded while fighting in the war. Before dying, Evadne prophesies Raymond's death, a prophecy which confirms his own suspicions. Raymond's intention to enter Constantinople causes dissension and desertion amongst the army because of reports of the
plague. Raymond goes alone to find that Constantinople has been seemingly deserted and soon dies in an explosion, the result of a trap laid by the Turks. He is taken to a site near Athens for burial. Perdita refuses to leave Greece, but Lionel drugs her and brings her aboard a steamship, believing it to be in the best interests of Clara. Perdita awakens and, distraught at Raymond's death, throws herself overboard and drowns. In 2092, while Lionel and Adrian attempt to return their lives to normality, the plague continues to spread across Europe and the Americas. The appearance of a
black sun causes panic throughout the world, and
storm surges flood coastal towns across Europe. At first, England is thought to be safe, but soon the plague reaches it. Ryland, recently elected
Lord Protector, is unprepared for the plague, and flees northward, later dying alone amidst a stockpile of provisions. Adrian takes command and is largely effective at maintaining order, although the plague rages on summer after summer. Ships arrive in Ireland carrying survivors from America, who lawlessly plunder Ireland and Scotland before invading England. Adrian raises a military force against them and ultimately manages to resolve the situation peacefully.
Volume 3 The few remaining survivors decide to abandon England, looking for an easier climate. On the eve of their departure to
Dover, Lionel receives a letter from Lucy Martin, who could not join the exiles because of her mother's illness. Lionel and Idris travel through a snowstorm to assist Lucy. Idris, weak from years of stress and maternal fears, dies along the way during the fierce weather. Lionel brings her body to
Windsor Castle, interring her in
St George's Chapel, and is met by the Countess, who reconciles with Lionel at Idris' tomb. Lionel recovers Lucy (whose mother has died), and the party reaches
Dover en route to France. In France, Adrian learns the earlier emigrants have divided into factions, amongst them a fanatical religious sect led by a
false messiah who claims his followers will be saved from disease. Adrian unites most of the factions, but the fanatics declare their opposition to Adrian. Lionel sneaks into Paris, where the cult has settled, to try to rescue Juliet. She refuses to leave because the impostor has her baby but helps Lionel escape after the impostor's followers imprison him. Later, when her baby sickens, Juliet discovers the impostor has been hiding the effects of the plague from his followers. She is killed warning the other followers. The impostor commits suicide, and his followers return to the main body of exiles at
Versailles. The exiles travel towards
Switzerland, hoping to spend the summer in a colder climate less favourable to the plague. By the time they reach Switzerland, however, all but four (Lionel, Adrian, Clara, and Evelyn) have died. They spend a few relatively happy seasons at
Switzerland,
Milan, and
Como before Evelyn dies of
typhus. The survivors attempt to sail across the
Adriatic Sea from
Venice to
Greece, but a storm destroys the boat and drowns Clara and Adrian. Lionel swims to shore at
Ravenna. Fearing to be the last human left on Earth, Lionel follows the
Apennine Mountains to
Rome, befriending a
sheepdog along the way. A year passes without anyone else entering Rome, and Lionel resolves to leave with his dog and live the rest of his life as a wanderer of the depopulated continents of Africa and Asia looking for other survivors. The story ends in the year 2100. ==Themes==
