Publisher's Synopsis
When the worlds of Ranger's Apprentice and Brotherband cross over, action and adventure are guaranteed! King Duncan of Araluen has an urgent mission for Hal and the Heron Brotherband. One assassination attempt on Princess Cassandra was foiled. But the killers won't be satisfied until they have fulfilled their honour-bound duty. The Herons, along with Ranger Gilan, set off for Arrida. There they must track the cult of killers across the desert, and infiltrate the cult's mountain lair to find their leader - and stop him. But the giant assassin isn't the only threat they will face.
