Kalfar’s The Spaceman of Bohemia is an extraordinary vision of the endless human capacity to persist and risk everything in the name of love and home. Nors’ Mirror, Shoulder, Signal is a witty, gut wrenching, lyrical tale of one woman’s journey in search of herself when there’s no-one to ask for directions. The Danish novelist is longlisted for the 2017 Man Booker International Prize. They talk to Rosie Goldsmith.
