More like 3 3/4 stars.It's a light read. An easy read. The letter format doesn't annoy and is well used. You hear or learn about things from different people and it adds to the charm of this novel.Because that's what it is, it's charming. Not in a cutesy way because it does take on some difficult subjects. How does one survive a terrible period in this case Guersey's German occupation during WW2? Humans can be true to their values and humans can be animals to one another. This is the stories of people who found the strength to go on and survive through friendship and reading books. This Guernsey Literary and Potato Peel Pie Society is the lifeboat that the characters grab on and held on to in order to survive. Even Juliet who is writing about the events, who wasn't there but finds herself involved beyond anything she ever thought possible. Charming with lots of interesting characters maybe some are a little too excentric (I'm thinking Isola here) but still not enough to annoy me.
