When Santa arrives at a child's house on Christmas Eve, does he go down the chimney feetfirst or headfirst? What if he gets stuck? What if there's no chimney? Maybe he slides under the door, as thin as a piece of paper? Or is it possible he pours himself through the tap? What happens once he's inside? Channeling a child's fanciful explanations, this latest collaboration by a bestselling team will find a secure spot among family Christmas traditions. 3+ From the multi-award-winning duo of Mac Barnett and Jon Klassen!
