What is the author's style in Auschwitz: True Tales from a Grotesque Land by Sara Nomberg-Przuytyk?

The perspective of Auschwitz: True Tales from a Grotesque Land is two-fold that of the translator and the editors and that of the author, Sara Nomberg-Przytyk. The translator has a forward and the editors have an afterward, the first of which comments on how the translator tracked down the author and the history of the text, whereas the latter engages in literary criticism of the text.
