Isaac, a student at the church of St. Damascus, is called to perform his final test of the year. Lord Jericho, a corrupt leader of the church, trains students in the art of killing dragons and stealing their magic. Isaac feels very different from his peers, as he is the only one who refuses to participate in this sacrificial act. But in his fifth year at the church, he finally gives in to Lord Jericho's ways. Appalled with himself for sacrificing one of the sacred creatures, Isaac seeks redemption. He breaks church rules and stumbles upon a much deeper, horrifying truth. With the help of his bunk-mate Boyd and a bright girl named Elaina, Isaac battles to restore peace between his church and the lost dragons of the land.
