I have just finished a lovely book called The Children Who Lived In A Barn by Eleanor Graham. It has been reprinted by Persephone Books, a publisher specialising in "rediscovering" writers, mostly female, from the 20th century (they have a website).
Eleanor Graham's book was probably originally written for children, but I think adults of my generation would enjoy it more than my own progeny. It's set in the 1930s, and is about 5 children whose parents rush off to look after a sick Granny leaving them to fend for themselves. This in itself seems quite amazing to us now, but the plot thickens when the parents don't come back. The children, led by the indomitable oldest sister, manage to survive, and even to go to school, whilst living in a barn lent to them by a local farmer. The story is very much of its time, with wonderful period detail - I suppose in some ways it's a bit "Famous Five-ish" but much more realistic, as the children struggle with day to day living whilst resisting the unwonted attentions of the local busybodies.
Persephone have republished some really good books - "Miss Pettigrew Lives for A Day" (which was unfortunately made into a less than inspiring film), and "No Eggs and Few Oranges", a journal of life in London during the war, being another two that I liked. My absolute favourite is probably "The Fortnight In September" by RC Sherriff - it's about an ordinary 1930's family's annual trip to Bognor Regis, but it's written in such a beautiful, simple style, and the characters are so sympathtically drawn, that I was really sorry to finish it - although I must admit that my enthusiasm may stem partly from the fact that I spent many childhood holidays at Bognor.
I have been reading quite a few old children's books lately, and have also very much enjoyed re-reading The Otterbury Incident, and Noel Streatfeild's Ballet Shoes. Streatfeild's book about her own early years "A Vicarage Childhood" is also a great read - she was brought up in a 1920s vicarage, banned from doing just about anything on Sundays and not allowed to go to parties in Lent - but the book isn't miserable, and it's a good record of what life was like for a middle-class child of that time.
Apologies if any of these books have been mentioned before,
