At 22, Marianne Ihlen travelled to the Greek island of Hydra with Norwegian writer Axel Jensen. While Axel wrote, Marianne kept house, until Axel abandoned her and their newborn son for another woman. One day while Marianne was shopping in a little grocery store, in walked a man who asked her to join him and some friends outside at their table. He introduced himself as Leonard Cohen, then a little-known Canadian poet. Complemented by previously unpublished poems, letters and photographs, So Long, Marianne is an intimate, honest account of Marianne's life story.
