I recently read The Guernsey Literary and Potato Peel Pie Society by Mary Ann Shaffer and Annie Barrows. It's a novel set in London and on Guernsey Island just after World War Two. I didn't know before that Guernsey (in the English Channel) was occupied by the Germans during the war; they were hoping to use it as a stepping stone to occupying the UK. Children were sent away from Guernsey for their safety to live in the British countryside.
This was a brilliant novel, written as a series of letters to and from a young writer in London. She makes friends with the members of a literary society on Guernsey and eventually visits them.
I bought this book at the Oxfam shop in Central HK and I think it came from Costco in Canada - see the bilingual sticker.
