Time Shelter is the International Booker Prize-winning novel by Bulgarian author Georgi Gospodinov, a brilliant and thought-provoking exploration of memory, nostalgia, and the passage of time. The story follows Gaustine, an enigmatic psychiatrist who creates "clinics of the past," where each floor recreates a different decade to help people with Alzheimer's disease recover lost memories. As the idea spreads beyond medicine, entire societies become captivated by nostalgia, forcing nations and individuals to confront their histories and identities. Blending satire, philosophy, and speculative fiction with elegant prose, the novel examines themes of memory, history, identity, aging, politics, loss, belonging, and the human longing for the past. Inventive and deeply moving, Time Shelter is a remarkable meditation on time, remembrance, and the future.
