This novel is a blend of fiction, autobiography, and philosophical musings that explores the nature of forgetting, the power of laughter, and the struggle for personal and political freedom. Set against the backdrop of the political turmoil in Czechoslovakia in the 20th century, it follows the interconnected stories of various characters, including a man who is expelled from the Communist Party, a young woman in love with a man whose father was a political prisoner, and a couple who flee to America. Throughout, the book delves into the ways in which personal and collective memories shape identity and history.

The narrative centers around an elderly man who has spent his life compacting paper and books into bales in a decrepit cellar, using a hydraulic press. Despite the menial nature of his job, he has cultivated a deep love and profound knowledge for literature, philosophy, and art from the books that pass through his hands, many of which he rescues from destruction. The story is a poignant exploration of the power and resilience of the human spirit in the face of a dehumanizing, totalitarian regime, and a meditation on the enduring value of art and the written word. The protagonist's intellectual journey and his resistance to the oppressive forces around him serve as a metaphor for the survival of culture and individuality under oppressive conditions.
