There are kids' books written to appeal to kids, and there are kids' books like FEATHERS, written to appeal to the adults who buy the books for kids. There's almost always at least one of the latter type among the Newbery winners. They tend be cerebral rather than emotional, to involve Big Ideas, such as racism, poverty, and religion, but they are often rather skimpy on actual, you know, story.
That's not to say that it isn't good -- it is. It's beautifully written, lyrical, thoughtful, at times even wise. There are undoubtedly some kids, patient and experienced readers who don't need a story to keep them turning the pages, who will enjoy this, maybe even love it. But not many. Mostly it will be loved by the adults who make the purchasing decisions. But for those who assume that a Newbery Honor means it's a good book to recommend to kids, here is, yet again, proof of the falseness of that assumption.
