Karlsruhe Germany during 1940's

I was born in Karlsruhe Germany in 1948 and came to US a yr later. My mother was born in 1923 in Karlsruhe. I did not live with her growing up and would like to have information on what her life would have been like as a teenager and young adult during the reign of Hitler and World War II during the 1940's. I am writing a book and want any information that someone could give me to understand what she must have gone through. I have a few stories which I remember that she shared but can't ask her any questions now that she is deceased. Thanks for any help.
