Palmer wrote that "although it is certainly not heavy handed in its exploration of what might be called 'the Dutch-Canadian experience,' Hendrika Ruger makes clear that the stories and poems collected here do represent recent attempts by the children of immigrants to examine the history of their parents' migration and struggle and to give their discoveries academic or literary form.
