Arthur, now eighteen, is missing, and Merlin must find him before a shadowy pursuer catches him first.With the High King and his kingdom caught in a trap of sinister deceit, Merlin has to find a way out before all is lost. Having everything to fight for, and almost nothing to fight with, Merlin and Arthur must rally Britain’s warriors against three overwhelming enemies: Saxen hordes in the south, Picti raiders in the north, and a chilling new enemy that has arisen in the west. At the same time, Morgana brings Merlin’s deepest fear to life and sets a horde of werewolves loose to destroy Britain. But when the secret purpose of this nightmare is finally revealed, will Merlin and Arthur find a way to survive—without unleashing an even greater evil?

Betrayal. After destroying the sinister Druid Stone and freeing his people from its dark control, Merlin finds himself a royal advisor without a king. Along with his friend Garth and Natalenya, his betrothed, Merlin treks north with the orphaned Arthur in hopes of keeping the young ruler safe from soldiers misled by their turncoat captain. Relentlessly pursued by his old nemesis Vortigern, Merlin and his band make for the fortress of Dintaga. But dangers multiply when Merlin realizes that Vortigern is not his only enemy. Even his own sister appears bent on Merlin's destruction. As the threat on all their lives increases, Merlin discovers their only hope is sailing to the lands of eternal darkness and once again cleansing the world from an ancient and powerful evil.
