In the world in which Lizbet Lenz lives, the sun still goes around the
earth, God speaks directly to his worshippers, goblins haunt every
cellar and witches lurk in the forests. Disaster strikes when Lizbet's
father Gerhard, a charming scoundrel, is thrown into a dungeon by the
tyrant Hengest Wolftrow. To free him, Lizbet must cross the Montagnes du
Monde, globe-girdling mountains that reach to the sky, a journey no one
has ever survived, and retrieve a mysterious book. Lizbet is desperate,
and the only one who can help her is the unpleasant and sarcastic witch
girl Strix. As the two girls journey through the mountains and into the
lands of wonder beyond, on the run from goblins, powerful witches, and
human criminals, Lizbet discovers, to her horror, that Strix's magic is
turning Lizbet into a witch, too. Meanwhile, a revolution in Heaven is
brewing.
