The book, entirely written in letter format, was a welcome change from the standard novel, though it still took some getting used to. On the back jacket, I read a review saying, "I kept forgetting they weren't my actual friends and neighbors" and I had a hard time believing that you could possibly become attached to these characters. But I did. 
 The story takes place on Guernsey, as the title suggests, at the end of WWII. The letters together tell the story of what the islanders went through over the five years that their little island was occupied by Germans. It was at times delightful, and gut wrenching at others. 
 Although this is not the type of book I would normally feel compelled to read, I did enjoy it immensely, and definitely recommend it to lovers of historical fiction.
