Greta and Matthias are worried. Their daughter Holly is sick and no-one knows what is wrong. The doctor cannot help, and Holly gets paler and sleepier with every passing day.
Then every parent’s worst nightmare: Holly disappears.
The only clue Greta can find is an odd little doll made of tree-roots arranged where Holly has been playing tea-parties. They are totally at a loss, and terrified for their daughter.
But just when everything is at its blackest, hope comes in the shape of a hare. Can it really be the same that helped Greta during the winter of the Snowmaiden? Who is the owner of the tree root doll?
