Through the diaries and personal papers of a German woman, Vera Conrad, this book documents her wartime experiences and deepens our understanding of the complex experiences of trauma and grief that National Socialist supporters experienced. Building on scholarship about mourning and widowhood that largely focuses on state policies and public discourses, This Horrible Uncertainty provides an interpretive framework of people's perceptions of events and their capacity to respond to them. Using a history of emotions approach, Erika Quinn establishes that keeping the diary allowed Conrad to develop different selves in response to her responsibilities, fear, and grief after her husband was declared missing in 1943.
