This is the third in what is intended as a quartet of books by Sam Usher, aimed at readers aged three to five.

This felt like a book of two halves on my first reading. 

First we meet Boy. On a grey day, he's bored. But Grandad has plans.

They set out in the horrible weather to buy some bits and pieces which Grandad takes home and transforms into a wonderful sledge.

Then they go outside into what has become a winter wonderland and embark on a mission to find a lost dog. With the sledge, though, their adventure knows no bounds.

It is an endearing, magical book and perfect as a Christmas or winter gift.
