When Mary Shelley published Frankenstein in 1818, she created a legend that, like the monster of her story, grew far beyond anything she could ever have dreamed of, or that anyone could ever control. With one book, she founded the field of science fiction, pushed the gothic into new territory, and gave us an unforgettable character capable of being monster, man, and metaphor, a symbol simultaneously of the potential and perils of science--even of humanity itself.

The novel was originally published in three volumes in March 1818. In 1831, a different publisher issued a single-volume edition that had been heavily rewritten by an older Mary Shelley. That edition served as the standard Frankenstein for well over a century. In recent decades, however, growing awareness of the role of Shelley's husband, Percy Bysshe Shelley, in the revision process, and corresponding interest in giving readers access to the original text from Mary Shelley's hand, has led to increasing attention to the original 1818 edition.

This edition reproduces the text of the 1818 edition with the addition, clearly indicated within the book, of minor changes that Mary Shelley made by hand in 1823. It also preserves the original three-volume structure within this single book, helping readers better understand the symmetries within the story as Shelley constructed it. Explanatory notes, meanwhile, explain references and provide historical and cultural context.

The result is a new look at a lasting classic, one that has as much to say to readers today as it did when first published more than two centuries ago.
