"That's the Hello, Goodbye Window. It looks like a regular window, but it's not" The kitchen window at Nanna and Poppy's house is, for one little girl, a magic gateway. Everything important happens near it, through it, or beyond it. Told in her voice, her story is both a voyage of discovery and a celebration of the commonplace wonders that define childhood. It is also a love song devoted to that special relationship between grandparents and grandchild. Norton Juster is an architect (retired), a teacher (retired) and a grandfather (just warming up), as well as a writer. He is the author of the classic children's book The Phantom Tollbooth and the mathematical romance The Dot and the Line. The Hello, Goodbye Window is his first picture book. Chris Raschka is the writer and illustrator of the HBFC titles Happy to Be Nappy, Little Tree, Be Boy Buzz and Skin Again, as well as the Thingy Thing series, which he wrote and illustrated. Raschka's Yo! Yes? is a Caldecott Honor Book.
