"Shouldn't we be orphans?" wonders one of the Willoughby children. The four siblings have not been treated fairly by their parents, and so they plot to become orphans. But in this spoof of classic children's literature for readers 8 to 12 by the Newbury-winning author of Number the Stars and The Giver, the grown-up Willoughbys are formulating their own plan, one inspired by Hansel and Gretel.
