After a gap of ten years, Michelle Paver decided to return to the world of Wolf Brother, with three further gripping stories, published by Head of Zeus.

I was so thrilled and touched when Michelle asked for me personally to work on the covers, and it was a really lovely experience.

The first of the new stories takes place in a frozen world of ice caves and ancient mammoths. At one time the mammoth was going to be the cover star, but it proved too big to fit!
