"Eastwick" is a novel written by author John Updike, published in 1984. The story is set in a fictional town in New England and follows the lives of three women—Joanna, Frances, and Jennifer—who discover their unique powers and form a bond. The narrative explores themes of friendship, empowerment, and the complexities of female identity. The novel was later adapted into a film in 1987, titled "The Witches of Eastwick," starring Jack Nicholson, Cher, Susan Sarandon, and Michelle Pfeiffer. The film retains the core elements of the book while adding a supernatural twist, focusing on the women's interactions with a mysterious man who disrupts their lives.
