I've seen this book on the bestseller lists and the Barnes and Noble's table and recommended lists but didn't give it a try because I didn't think I'd like it....I was wrong :) And, I'm really glad I tried it. It's a light read and the characters are really lovable. But the thing that I loved the most about it was the history that winds through it. Set in the English Channel Islands just after the end of WWII, it deals with a lot of dark topics but it definitely isn't a dark book. I learned a lot about England during WWII and the German Occupation of Guernsey Islands. It doesn't read like a history lesson, though. If you're looking for quick read with a little bit of history, love, and lots of witty characters, this is your book :)
Oh, and it's written as a series of letters which is why I wasn't at first interested. But, I think that format really worked for this story. Enjoy!
