I bought this for my son and thought I'd give it a whirl, too. The story is very powerful and engrossing. The comic format increases that power, I think, because of the exaggerated visuals that bring across the physical impact of the war. This is a moving family story told from a boy's point of view. As if the hardship and desperation of wartime Japan weren't enough, the atomic bomb falls and makes the horror story complete. And it really is a horror story above all.
I was happy to see my 13-year old intently reading it. I'm glad he did.
