And Stones from the River, by Ursula Hegi - not strictly a war time book, but it features high and is absolutely mesmerizing

Some old books with relatively new editions: "A square of sky" by Janina David - read it as a child & still find it touching; "Fly away home" by Christine Nostlinger - a child's perspective from the 'other' side

Closely Observed Trains by Bohumil Hrabel

One of the best I've read is called The Nazi Officer's Wife by Edith Hahn
Would also say When Hitler stole Pink Rabbit for a child's eye view.

The Boy Who Loved Anne Frank is interesting.

The Book Thief?

and The War and After by Ann Karpf.

and from an earlier period, have you read Testament of Youth? I'm not sure if it's one of those things that everyone has read so it's embarrassing to even recommend it, but I have the feeling it's not as popular as it used to be. I love it though.

Would second When Hitler Stole Pink Rabbit. My mother just read it and was keen to tell me how good it was - I've only been telling her that for 25 years

When I Lived in Modern Times by Linda Grant may be of interest too. A damn good book.

OK , so slightly different but still on war and made me think about it for days is Birdsong by Sebastian Faulks. Broke my heart that book.

Oh the ending! How did the author manage to make it so believable?

It could so easily been mawkish and far fetched.

Still - better not give it away

And weep & weep, at his ignorance & innocence & sweetness throughout, but most of all at the ending...

I didn't hear it on the radio. I'll look out for it!
