Catrin Collier was born into a close Welsh family in 1948 - very aware of her dual heritage. The war was recent, her mother German, her father Welsh. She loved her German grandmother, spent summers with her in Germany, and couldn't understand how ordinary Germans had allowed the monstrous Nazi regime to flourish. After working in various jobs, she became a full-time writer in 1994. In 1995 she accompanied her mother when she returned to East Prussia (now Poland) for the first time in fifty years. There she read the diaries that her mother and grandmother had kept and talked about life under the Nazis. ONE LAST SUMMER is the result of those conversations. She lives with her husband in Wales.
