Almost fooled me! The book's well-drawn graphic novel style, spare pacing, and enchanting representation of a family in a power outage just about masked the story's attempt to teach us all a lesson. Once more, the fact that I agree with the message doesn't help. I don't think the sermon is in general a genre of literature. And this is the second (or third) book in two weeks to try to tell me to just turn off the lights and enjoy life without gadgets.
