A Lovely Tomorrow by Mabel Esther Allan

From the back of the book:
It was New Year's Eve, 1944, that the V2 rocket cut Frue Allendale's life in half. She had only happiness to look back on, and only blank tomorrows ahead. To leave London where she was a drama student seemed the end of the world to Frue. Clinging to the memory of her dear, loving parents, Frue took opposition and animosity toward her great aunt and her new life in the country.
