After the events of the previous book: The Ruins of Gorlan, Ranger apprentice Will is settling into his life as a protector of king and country. But war is coming.
An evil tyrant Lord Morgarath threatens to overrun the whole of Araluen with his army of fierce beasts known as Wargals.
Will is chosen, along with two of his friends to be part of a special army sent to the southern country in Araluen: Celtica.
But when they arrive they find the towns and surrounding land deserted. It appears the evil hand of Lord Morgarath has been at work.
Far away from help it is up to Will and his friend Horace to save Araluen.
