We first met novelist Karen McMillan's Polish characters in Warsaw, the Paris of the East, during the Second World War. In her sequel, the surviving family members who suffered appalling hardships under the Nazis, move to the Paris of the West - San Francisco. Unlike many migrants of the time, Celina, her father, shell-shocked husband and journalist brother in law get a big helping hand from family who moved to the States from Poland before the war. But even with financial support, the new migrants struggle to establish a new life in a very different country. Lynn Freeman talks to Karen about The Paris of the West.
