Five years have passed, & Will has finally become a Ranger, with his own fief to look after. He soon learns that even sleepy little island fiefs have problems enough to keep him on his toes.
Then he & his old friend Alyss are thrown into a terrifying new adventure, investigating the truth behind rumours of sorcery in a remote northern fief. As he stands in the forest, hearing eerie voices, with the horrific figure of the Night Warrior looming in the fog, Will must ask himself one question: is there a rational explanation... or does sorcery really exist?
This is the fifth book in the enthralling Ranger's Apprentice series.
