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.

"Happy Days" is a play that revolves around the life of Winnie, a middle-aged woman who is buried up to her waist in a mound of earth, with her situation worsening in the second act as she becomes buried up to her neck. Despite her predicament, Winnie maintains a sense of optimism and routine, often reminiscing about the past and engaging in one-sided conversations with her taciturn husband, Willie, who is largely invisible offstage. The play delves into themes of human resilience, the passage of time, and the search for meaning in the face of an absurd and unchanging predicament, with Winnie's relentless cheerfulness contrasted against the bleak and inexplicable situation she finds herself in.
