A wild world of magical creatures and heroic adventure from
the extraordinary imagination of Philip Reeve. The squabbling
goblins who live in the great towers of Clovenstone spend their
time fighting and looting. Only clever young Skarper understands
that dark magic created by a vanquished sorcerer is rising again.
From the lands of men come fortune-seekers - and trolls,
giants, cloud-maidens, boglins, swamp monsters, tree-warriors and
bloodthirsty goblins are swept into a fabulous magical conflict
to thrill all fantasy fans.
