In the 1930s, women and men from across the world made their way to Spain to be part of what they saw as a historic fight for freedom from fascism. Tomorrow Perhaps the Future follows extraordinary outsiders who were determined to live out their lives with courage and conviction.

Sarah Watling weaves together the experiences of a host of writers and activists, including Nancy Cunard, Martha Gellhorn, Jessica Mitford and Virginia Woolf, and searches out the stories of the photographer Gerda Taro and the Harlem nurse Salaria Kea. Throughout, she explores solidarity, art and resistance, finding answers that are as vital today as they were almost a century ago.
