A unicorn banished from her herd. An untrained sorceress who is desperate to advance her craft. A huge boy who does not know to grasp his destiny. A sorcerer of great power who must find the wisdom to save his own life. Kingdoms mobilized to rescue a sacred captive, and others coming to possess her. A dragon who must challenge a powerful rival to save an enemy who is his closest friend. And in the midst of all this chaos, a young unicorn must stave off wars and sinister plots to rescue the heart of one who would dare to steal her freedom, and she must find a way to protect what she holds most precious.
