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 Complemented by previously unpublished poems, letters, and photographs, So Long, Marianne is an intimate, honest account of Marianne's life story — from her youth in Oslo, her romance with Axel, to her life in an international artists' colony on Hydra in the 1960s, and beyond. The subject of one of the most beautiful love songs of all time, Marianne Ihlen proves to be more than a muse to Axel and Leonard; her journey of self-discovery, of romance and heartache is lovingly recounted in So Long, Marianne.
