In Norton Juster's brilliant sequel to Caldecott winner The Hello, Goodbye Window, Nanna and Poppy never quite know who will show up for a visit-Sourpuss or Sweetie Pie. In a heartbeat, their precious granddaughter can change from a pure joy to a real grouch. One moment she's kind and cooperative, and the next she's stubborn and mean. And when she lies down to sleep as Sweetie Pie, her grandparents wonder what she'll be like when she wakes up. But Nanna and Poppy will love her, no matter what.
