The starting point for the writing process was reading a biography of Sophie Scholl (see the
References section), the youngest and only female member of the non-violent German resistance group
Die Weiße Rose (The White Rose), who operated against the Nazi regime until their capture and execution in 1943.
If not in its actual storyline, thematically, the novel refers heavily to this real-life story. An important theme that is being addressed is the connection between ideas, ideals, and ideologies; specifically, how ideas develop into ideologies, and what happens when ideals are destroyed by an ideology.
The original context for this basic theme was the formation of Nazism from a number of pre-existing myths, legends, and ethnic prejudices, and the subsequent elimination of humanist principles by Nazism. In the novel, the scope of this theme is limited, with an emphasis on personal rather than global conflicts, which play out in the context of the end of the Cold War.
Even so, explicit references to the Second World War are being made through the backstory of the novel, in which one of the key inciting events is a direct reference to the execution of the White Rose members, and which, after a fifty-year gap, gives rise to a series of violent crimes. The novel, therefore, is centrally concerned with the passing of unresolved conflicts from one generation to the next. Connected to this issue are "mirrored" (either parallel or inverted) storylines, which play a recurring role throughout.
Another important aspect is the contrast between the objective reality of the physical world, and subjective realities that are filtered through an individual’s understanding of the world, including their biases and prejudices, which links back to the topic of ideologies. This also involves fundamental concepts of semiotics – or the study of signs – and addresses the contrast between moral absolutism and moral ambiguity, as well as the potential impact of false narratives.
