I am just finishing up this book and will be very sorry to see it end. I have really enjoyed it.
The Guernsey Literary and Potato Peel Pie Society by Mary Ann Shaffer and Annie Barrows (an aunt and niece team). It takes place in London and the Channel Islands (Guernsey) after WWII and is in the format of a series of letters.
The letters are just wonderful and each one allows more in depth discussions between the participants. It is very educational too, but does not lecture on the history, it is just part of the conversations. The characters are what are to me as real people, real life experiences during a horrific period and some real fortitude of character with just the right amount of humor and romance.
I highly recommend it. (Oh, and if you read it, you will find out what potato peel pie is all about)
