Mary Shelley (then Godwin) and Percy Bysshe Shelley were visiting their friend Lord Byron in Geneva one rainy summer. With the weather against them, they decided to spend their time writing ghost stories for each other. Frankenstein is Mary Shelley’s submission to their contest, later published anonymously in 1818. Victor Frankenstein, a strange but brilliant scientist, discovers a method of imparting life to inanimate matter. The Monster is thus born: a hideous, 8-foot-tall creature of muscle, speed, and intellect. Frankenstein’s rejection of his appalling creation sends it into a spiral of despair, and Frankenstein’s life is never the same. Considered by many to be the first science fiction novel, Frankenstein is a powerful narrative that explores complex themes of belonging, morality, and the consequences of the power over life and death. This edition is based on Shelley’s revised 1831 edition.

Dracula is one of the most famous horror novels, responsible not just for introducing the eponymous Count Dracula, but for laying the foundations for many of the common tropes we see in modern horror fiction. Count Dracula isn’t the first vampire to have graced the pages of Western literature—that honor belongs to Lord Ruthven in “The Vampire,” a short story by John William Polidori—but Dracula is the vampire on which the modern vampire trope is based. Dracula wasn’t as famous in its day as it is today; readers of the time seemed to enjoy it as nothing more than a good story, and Stoker died nearly penniless. But its long-lasting influence is undeniable, and for all its age Dracula remains a gripping, fast-paced, and enjoyable read.

The Picture of Dorian Gray was first published as a serial in Lippencott’s Monthly Magazine, and the publishers thought it would so offend readers that they removed nearly 500 words without Wilde’s approval. Wilde soon expanded it and republished it as a novel, including a short preface justifying his art. Even though his contemporaries considered it so offensive that some argued for his prosecution, Dorian Gray today survives as a classic philosophical novel that explores themes of aestheticism and double lives. Couched in Wilde’s trademark cutting wit, Dorian Gray is still being adapted today, with Dorian and his moldering portrait remaining cultural touchstones.

The Strange Case of Dr. Jekyll and Mr. Hyde is the classic novella of split personality. Stevenson wrote it in just a few days while sick and bedridden, and famously burned the first draft after his wife suggested it should be written as an allegory and not as a story. He re-wrote it in three to six days, and after a few weeks of editing and revision he published what would become one of his most famous and best-selling works. The story follows a London lawyer as he investigates the relationship between a brilliant scientist and a misshapen misanthrope. As the link between the two becomes clearer, Jekyll and Hyde develops into an allegory on the nature of good and evil.

Griffin, a scientist, has devoted his life to the study of optics. As his work progresses, he invents a method of making a person invisible. After testing the experiment on himself, he comes to realize that while the experiment was a complete success, he has no way of reversing his invisibility. Written in a time of rapid scientific progress and industrial development, Wells uses Griffin’s struggle with his condition and descent into obsession and madness to reflect on the dangers of unbridled scientific progress untempered by compassion or humanity. The Invisible Man was initially serialized in Pearson’s Weekly in 1897, after which it was published as a whole novel that same year.

Dr. William Dyer of New England’s Miskatonic University recounts his experiences on an Antarctic expedition leading to strange, enormous mountains deep within the frozen continent, hiding prehuman horrors only spoken of in esoteric tomes. Reflecting H. P. Lovecraft’s interest in the Antarctic—a continent still very unknown in the 1930s—this story gives a detailed account of the geology and history of Lovecraft’s universe. The dry, scientific text gradually becomes more suspenseful as the expedition uncovers more and more of the cosmic horrors Lovecraft became famous for. Taking inspiration from Edgar Allen Poe’s Arthur Gordon Pym and geological discoveries in his time, as well as building on his world established in previous works, At the Mountains of Madness establishes a story following the natural sense of mystery evoked by the frozen and uninhabited southernmost continent.
