The Scorched Earth Chronicles. Book One The Omtar Expedition, #1

When the sky burns, the world remembers. Humanity's final ordinary day ends without warning. A colossal alien vessel-ancient, and impossibly advanced-falls from the heavens and shatters the fragile balance of nations. Cities tremble. Governments fall. New alliances form in the shadow of something no one understands. Across the planet, scattered survivors and unlikely leaders rise from the chaos: a northern hunter who recognizes the invaders from stories older than memory; a desert sheikh and a runaway prince forced into an uneasy pact; scientists, soldiers, and civilians drawn together by a single truth-Earth is no longer theirs alone.
As the Omtar Expedition reveals its purpose, humanity faces a choice: unite or be extinguished. Every culture, every belief system, every buried myth suddenly matters. And in the silence after the first strike, whispers spread that the invaders are not the only ones watching. The Scorched Earth Chronicles begins with a world on the brink, a tapestry of intersecting destinies, and a war humanity never asked for-but must survive.
