Omby-Amby is different from everyone else in Emerald City. Yet the very thing that makes him different is the one thing that he and his family have in common—green hair. All his life, he had been taught to believe in two things—kings and soldiers. Then the Wizard came from the sky and proclaimed liberty, and Omby-Amby abandoned everything to join his cause. He has battled for freedom, but no amount of blade training can prepare him for his greatest challenge—facing those he left behind. Omby-Amby returns to his conquered homeland—now enemy territory—where the past pierces the present, and the destiny of an entire family rests on the strength of a single nail.
