Can we know courage without first knowing fear? JC was just sixteen years old when he threw away fear with a chain of magic bindmetal, but now he wants the fear back. Almost a year after the final, fatal confrontation with the Obliviates, he finds himself consumed with the need to travel the Spiral of Worlds again--this time in search of the only people that can free him from his false courage to find out what kind of man he's really become. He must convince his friends to travel with him back to Onus in search of the Metalbreakers, and to do this he must convince them that it is finally time to learn the names of the last three Children of the Line. The two quests will lead them to enemies both new and old, a world of endless winter, and an event that will change the Spiral of Worlds forever. Can JC find the courage to break free of his fear... or will everything fall to ruin? Metalbreaker is Book 3 in the Spiralchain
