Rule Changer. Outcast, #3

The glass walls are fracturing, and Oriacan war drums roll toward Megalopolis. Racing across the razor-edged Glass Teeth Peaks, Fish, Ari, Weed, and Branch carry one impossible demand: unite Megas and Zoners or perish together. Betrayed by rebel armies, trapped by shape-shifting priests, and shadowed by a god of molten glass, Fish must become more than a breaker of chains--he must forge the rules of a new world.
Stand together, or watch prophecy turn to ash and the world to ruins.
