Digger Dog loves to dig up bones...the bigger the better. But for the biggest bone in the world, what will Digger Dog need? The biggest digger in the world, of course! All through the story, the diggers get bigger, the hole gets deeper and there is the most fantastic fold-out surprise at the end! It has all the ingredients for a brilliant picture book for pre-schoolers. By William Bee, illustrated by Cecilia Johansson.
