The first twelve pages of this graphic novel are devastating enough for me to wait a while before handing it to my 7-year-olds. But they are essential for setting up the story, with hope presumably being a big reason Emily accepts the responsibility she does. Amazing art, cool robots, and a story that's good but barely begun. It does feature one of my pet peeves of this type of story - when people are thrown in crazy, unexpected situations, wouldn't they ask more questions about where they are and what's going on and be a little more freaked out?I read this in an hour, and would suggest it for nine and up. We're planning to use it for a "Dig into Reading" book club for ages 9-12 this summer.
