The celebrated John Burningham opens the door to a child’s secret adventure in this new picture-book classic.What if you noticed a door in your bedroom that wasn’t there before? And what if it led to a passage to . . . the zoo? You might want to take just one little bear back to your room with you, or maybe just all the smaller animals. But how could you resist the penguins and the tigers and the birds? In this classic child’s fantasy featuring John Burningham’s delightfully expressive artwork, an unlocked door leads to pandemonium — and one little girl’s formidable voice reins in an entire menagerie.
