Writer Mary Shelley published her most famous novel, Frankenstein, in 1818. She wrote several other books, including Valperga (1823), The Last Man (1826), the autobiographical Lodore (1835) and the posthumously published Mathilde.
Early Life

Shelley was born Mary Wollstonecraft Godwin on August 30, 1797, in London, England. She was the daughter of philosopher and political writer William Godwin and famed feminist Mary Wollstonecraft — the author of The Vindication of the Rights of Woman (1792). Sadly for Shelley, she never really knew her mother who died shortly after her birth. Her father William Godwin was left to care for Shelley and her older half-sister Fanny Imlay. Imlay was Wollstonecraft's daughter from an affair she had with a soldier.
The Godwin household had a number of distinguished guests during Shelley's childhood, including Samuel Taylor Coleridge and William Wordsworth. While she didn't have a formal education, she did make great use of her father's extensive library. Shelley could often be found reading, sometimes by her mother's grave. She also liked to daydream, escaping from her often challenging home life into her imagination.

Shelley also found a creative outlet in writing. According to The Life and Letters of Mary Wollstonecraft, she once explained that "As a child, I scribbled; and my favourite pastime, during the hours given me for recreation, was to 'write stories.'" She published her first poem, "Mounseer Nongtongpaw," in 1807, through her father's company.

The family dynamics soon changed with Godwin's marriage to Mary Jane Clairmont in 1801. Clairmont brought her own two children into the union, and she and Godwin later had a son together. Shelley never got along with her stepmother. Her stepmother decided that her stepsister Jane (later Claire) should be sent away to school, but she saw no need to educate Shelley.
