For as long as he can remember, Heriot Tarbas has been plagued with fits, headaches, dreams, and nightmares that make him feel as if a part of his very self is being torn away. His visions are only whispered about in his quiet life on the family farm. But when the King of Hoad hears word of his powers and seeks him out to be a member of the royal court, it becomes clear that Heriot has a gift, and a valuable one. While Heriot unwillingly learns to use his mind-reading and other abilities to serve the king as his most trusted advisor, four remarkably different lives--that of a Hero, a Magician, a noble girl, and a Prince--weave their way, for better or for worse, toward his. When their paths finally converge in the midst of political upheaval, hand-to-hand battles, and burgeoning romances, Heriot must decide how he'll choose to use his magic--and what his destiny will be.

With a complex cast of characters set against a majestic land, award-winning author Margaret Mahy weaves her magic in a fantastical tale exploring the meaning of truth, freedom, and loyalty to one's greater destiny.
