Frankenstein by Mary Wollstonecraft Shelley

The novel begins with explorer Robert Walton looking for a new passage from Russia to the Pacific Ocean via the Arctic Ocean. After weeks as sea, the crew of Walton's ship finds an emaciated man, Victor Frankenstein, floating on an ice flow near death. In Walton's series of letters to his sister in England, he retells Victor's tragic story.
Growing up in Geneva, Switzerland, Victor is a precocious child, quick to learn all new subjects. He is raised with Elizabeth, an orphan adopted by his family. Victor delights in the sciences and vows to someday study science. Victor prepares to leave for his studies at the University of Ingolstadt, when his mother and Elizabeth become ill with scarlet fever. Caroline dies from the disease, and Elizabeth is nursed back to health.
After bringing the creature to life, Victor feels guilty that he has brought a new life into the world with no provisions for taking care of the "monster." He runs away in fear and disgust from his creation and his conscience. The monster wanders the countryside while Victor seeks solace in a tavern near the university. Henry Clerval appears to save Victor and restore him to health.
Alphonse writes to Victor telling him to come home immediately since an unknown assailant murdered his youngest brother, William, by strangulation. Justine Moritz, their housekeeper, is falsely accused of the murder of William, and she goes to the gallows willingly. Victor knows who the killer is but cannot tell his family or the police.
Victor explains to Walton that he felt responsible for William’s murder and Justine’s execution. Guilt-ridden and desperate to be alone, he climbed into the mountains, where he encountered the creature. The creature told Victor that he had survived for the past two years, hiding out in the woods and eating nuts and berries. Lonely and miserable, he realized that he was repulsive to other human beings. In the forest, though, the creature discovered a gentle peasant family living in a cottage; by secretly observing them, the creature learned to read and write. Then, in his jacket pocket, the creature found Victor’s journal and read of the experiments that led to his creation. Enraged, he concluded that it was Victor Frankenstein who was responsible for his misery.

After relating his story, the creature demanded that Victor re-create his experiment and construct another creature. The creature explained he was desperate for a companion who would not find him repulsive. If Victor does as he asks, he will go away with the new creature and never bother Victor again. Although wary of the proposal, Victor says he reluctantly agreed to the creature’s request.

Victor tells Walton that he set up a new laboratory in Scotland and began the work of creating a companion for the creature. But he was haunted by the thought that this new monster might be more evil than the original, and he was terrified at the idea of the two creatures creating a new, horrible race of beings. So instead of completing his task, Victor destroyed his work before giving life to the new creation. But the original creature was watching Victor in his laboratory. Furious, he swore revenge, vowing to torment Victor for the rest of his life. Later that night the creature strangled Victor’s best friend, Henry Clerval.

Several weeks later, Victor married Elizabeth Lavenza, a girl who was adopted by his family, and with whom Victor had always been in love. But after Victor and Elizabeth marry, the creature appeared on their wedding night and strangled Elizabeth to death. Grief-stricken over the death of Elizabeth, Alphonse Frankenstein, Victor’s father, died a few months later. In utter despair, Victor vowed to pursue the creature and destroy it. He chased the monster for months, finally arriving in the Arctic where he met Walton and his expedition.

Walton tells the remainder of the story in another series of letters to his sister. Victor, already ill when the two men meet, worsens and dies shortly thereafter. When Walton returns, several days later, to the room in which the body lies, he is startled to see the monster weeping over Victor. The monster tells Walton of his immense solitude, suffering, hatred, and remorse. He asserts that now that his creator has died, he too can end his suffering. The monster then departs for the northernmost ice to die.
