The book is a seminal work in Yiddish literature and folklore, centering around the concept of a dybbuk—a malicious possessing spirit from Jewish mythology. The narrative follows the tragic tale of a young bride in a Polish shtetl who becomes possessed by the restless spirit of her dead lover, who had been wronged by his own father and her father's broken pledge. The possession leads to a dramatic exorcism and a series of events that explore themes of love, betrayal, and the clash between the mystical and the rational, as well as the boundaries of life and death. The story delves into the rich tapestry of Jewish mysticism, community, and tradition, reflecting the cultural and religious tensions of Eastern European Jews before the First World War.
