Billy doesn’t talk much, but he’s a very good listener. He listens when Patrick has worries to share and sometimes, when the worries get too big, they disappear off on magical adventures where anything feels possible. And Patrick returns feeling big and brave . . .Brave enough that on this special snow day, he has the courage to say hello to the other children . . .This powerful and sensitive new picture book from David Litchfield captures the magic of imaginary friendship, the power of empathy and the importance of our friends – real or not – in helping us to navigate the world as we grow.
