When Owen Sheers discovers a book in his father's study he stumbles upon the life of an obscure relative: Arthur Cripps, lyric poet and maverick missionary to Rhodesia. Compelled by the description of Cripps' extraordinary life in Africa, Sheers embarks on a journey through contemporary Zimbabwe in an attempt to better understand his ancestor's devotion to the country and its people and the dramatic, often bloody, differences that echo across the years.
