In Snow we meet a boy and his grandad as they prepare for a day out in the snow. As the boy impatiently tries to get out of the door, his grandad understands that a little delayed gratification, particularly at Christmas time, is sometimes the best thing.

The boy is tortured by the sight of other children making the first marks in the snow. But still there are things to be done.

Driven half mad by the anticipation he begins seeing visions in the snow.

Finally they get out and discover more fun in the park than even the imaginative boy could have envisioned

The story concludes with the return home and a good thawing out in the kitchen. Grandad sits back with a cup of tea and quite justifiably looks very pleased with himself.

Sam Usher's style undoubtedly owes a lot to Quentin Blake, so much so he's said that 'I’ve appointed myself his unofficial apprentice – in the manner of a renaissance artist. He doesn’t know.' There's also a similarity to Uri Shulevitz's book of the same name. Both artists make full use of the white space, treating it as a blank canvas of the imagination on which amazing things can happen.
