The two worlds of Glandair and Iomard move magically together once every generation. Though they never touch, those with special talents can Walk between the worlds. This is a time when power shifts, magical abilities skyrocket, and a Hero arises to save the world from corruption. Lyanz, the current Hero, is safely away from the conflict for the moment: learning skills and strategies, biding his time for the confrontations to come, while every sorcerer on two worlds looks for him. But his contemporaries are not faring so well. Breith has found himself a slave, while Cymel has left home to become a Scholar and fallen in with a disreputable crowd. Meanwhile, the strongest sorcerers on both worlds are drawing together the strings of a plot that will change everyone's life forever - if they don't trip over each other's plans.
