The format of the book is a series of letters between an author, Juliet and members of a Literary Society on the island of Guernsey just after World War II. The island was occupied by the Germans for 5 years during the war, and Juliet decides to write a book based on their experiences. They start to tell her stories which are sometimes sad, tragic and funny. The personality of each person is revealed in their letters and also in the books that they like to read. Really enjoyed this book - a book that makes you feel good.
