After the events of Sons of the Oak, Fallion and Jaz, the sons of the great Earth King Gaborn, are now living as fugitives in their own kingdom. Their former home has been invaded and secretly controlled by supernatural being of ultimate evil. The sons are biding their time until they can regain their rightful places in the land.
Fallion seems destined to heal the world, and feels the calling to act. When he attempts to do so though, two entire worlds collapse into one, and nothing will ever be the same again. [from publisher web site]
