"Daisy Kildare is poor but her Aunt finds her a position as a companion to her employers' niece, Cynthia. There she meets Jake, the chauffeur's son, and life becomes easier to bear. When Jake goes to university, Daisy means to follow, but war intervenes and she starts work at a factory, and falls in love for the very first time."

That short synopsis doesn't do the story justice, I think. There's a lot more to the story than Daisy being poor and then falling in love. A crook, a tragic accident, and another accident - not quite as tragic, and due to the war - are also involved. But I've said enough. So, I'll just finish by saying that it was a good book, and that I hope the other Katie Flynn book I got from the library is as good.
