The Guernsey Literary and Potato Peel Pie Society by Mary Ann Schaffer. I first read this book with my local library book club at the beginning of 2012, I have since read it a second time and found it just as enthralling.

I loved that book too! I have been trying to talk one of my friends into reading it, but no luck yet! If you want to read it for a third time and haven't already, there is an excellent audio version of the book available.
