I liked this book. There needs to be a 3 1/2 star rating, because it's somewhere between "liked" and "really liked". I thought the story ended rather abruptly... you got the sudden feeling that the author suddenly tried panning out and giving the whole life perspective when she'd been progressing by days and months before that. The story, then, felt somewhat contrived, and you're left guessing on the main character's thoughts when up until that point they'd been fairly explicitly shared with you. What I really liked was the letters! I thought framing a story around the letters was great, and gave such a personal cast to World War II.
