It's 1946 and Juliet Ashton can't think what to write next. Out of the blue, she receives a letter from Dawsey Adams of Guernsey - by chance, he's acquired a book that once belonged to her - and, spurred on by their mutual love of reading, they begin a correspondence. When Dawsey reveals that he is a member of the Guernsey Literary and Potato Peel Pie Society, her curiosity is piqued and it's not long before she begins to hear from other members. As letters fly back and forth with stories of life in Guernsey under German Occupation, Juliet soon realizes that the society is every bit as extraordinary as its name

In 1946, writer Juliet Ashton receives a letter from a stranger, a founding member of the Guernsey Literary and Potato Peel Pie Society. And so begins a remarkable tale of the island of Guernsey during the German occupation, and of a society as extraordinary as its name.
