Pam Munoz Ryan's Echo
I'm an adult, so sometimes middle-grade books don't work for me, and this was one of those times. The concept was cool--there's a magical harmonica and it passes through the hands of three young people during the turbulent 1930s and 40s, with a very fairy tale framing device--and most of it was fine, but it was just TOO on the nose/moralizing/educational/cheesy/ SOMETHING. Not subtle, anyway. B.
