I picked up a copy of The Guernsey Literary and Potato Peel Pie Society and was surprised by the format. The story is told entirely by letters - mainly between residents of Guernsey, a writer and her editor.
"January 1946: London is emerging from the shadow of the Second World War, and writer Juliet Ashton is looking for her next book subject. Who could imagine that she would find it in a letter from a man she'd never met, a native of Guernsey, the British Island once occupied by the Nazis. . . As Juliet and her new correspondent exchange letters, she is drawn into the world of this man and his friends, all members of the Guernsey Literary and Potato Peel Pie Society."
Island at War was a miniseries based on another Channel Island, Jersey, and would be a good companion for the Guernsey Literary and Potato Peel Pie Society.
