A simple, wordless celebration of winter joy-with a delightful surprise ending What happens when you take a little snowball and try to make it bigger? You might roll it up a hill, you might even get some friends to help you roll it, until the snowball is huge. But what happens when gravity takes over? In this adorably hilarious, wordless board book, artist Giuliano Ferri uses clever die-cuts to bring humor and anticipation to a charming story of what happens when the snowball of your dreams goes off course.
