Dragonbards Trilogy, Book 1. As dark raiders invade the world of Tirror, a singing dragon awakens from her long slumber, searching for the human who can vanquish the forces of evil—Tebriel, son of the murdered king. Teb has found refuge in Nightpool, a colony of talking otters. But a creature of the Dark is also seeking him, and the battle to which he is drawn will decide Tirror’s future.
