Forged beneath twin suns, Zafir al-Shams—called the Instrument—leads a desert legion through sieges, betrayals, and night-black sorcery to break a tyrant that devours daylight. Steel flashes, cities burn, and mercy costs blood; yet wherever the sun strikes his blade, hope returns. A war-epic of blistering battles and quiet vows, where overwhelming power is tempered by duty to feed, heal, and spare.
