Reckless , av Cornelia Funke. Pojken har faktiskt en bror, inte en syster: flickan är brors flickvän.

With time running out, Jacob, Will, Clara and Jacob's vixen friend, Fox, journey to the witch's house ...
... on their mission to rescue Will, they travel cross country to the mountains underneath which the Goyl have built their capital city.
