the historical novels Valperga (1823) and Perkin Warbeck (1830), the apocalyptic novel The Last Man (1826) and her final two novels, Lodore (1835) and Falkner (1837). Studies of her lesser-known works, such as the travel book Rambles in Germany and Italy (1844) and the biographical articles for Dionysius Lardner's Cabinet Cyclopaedia (1829–1846), support the growing view that Shelley remained a political radical throughout her life. Shelley's works often argue that cooperation and sympathy, particularly as practised by women in the family, were the ways to reform civil society. This view was a direct challenge to the individualistic Romantic ethos promoted by Percy Shelley and the Enlightenment political theories articulated by her father, William Godwin. Life and career Early life Mary Shelley was born Mary Wollstonecraft Godwin in Somers Town, London, in 1797. She was the second child of the feminist philosopher, educator, and writer Mary Wollstonecraft and the first child of the philosopher, novelist, and journalist William Godwin. Wollstonecraft died of puerperal fever shortly after Mary was born. Godwin was left to bring up Mary, along with her older half-sister, Fanny Imlay, Wollstonecraft's child by the American speculator Gilbert Imlay. A year after Wollstonecraft's death, Godwin published his Memoirs of the Author of A Vindication of the Rights of Woman (1798), which he intended as a sincere and compassionate tribute.

Mary Godwin read these memoirs and her mother's books, and was brought up to cherish her mother's memory. Mary's earliest years were happy, judging from the letters of William Godwin's housekeeper and nurse, Louisa Jones. But Godwin was often deeply in debt; feeling that he could not raise the children by himself, he cast about for a second wife. In December 1801, he married Mary Jane Clairmont, a well-educated woman with two young children of her own—Charles and Claire. Most of Godwin's friends disliked his new wife, describing her as quick-tempered and quarrelsome; but Godwin was devoted to her, and the marriage was a success. Mary Godwin, on the other hand, came to detest her stepmother. William Godwin's 19th-century biographer Charles Kegan Paul later suggested that Mrs Godwin had favoured her own children over those of Mary Wollstonecraft. Together, the Godwins started a publishing firm called M. J. Godwin, which sold children's books as well as stationery, maps, and games. However, the business did
