The Last Fire. The Last Fire, #1

The world ended in ash. But one flame refused to die. In a shattered future where the sky is buried beneath endless clouds of ash, the last survivors of humanity cling to life in a fragile sanctuary known as Helios. For generations they have protected the final remnant of the old world-a mysterious Sphere that holds the fading spark of fire. When the Flame begins to die, the balance of the wasteland collapses.
Arden, a young warrior burdened by loss, is sent beyond the safety of Helios into the ruins of a forgotten world. His mission is simple: find a way to save the Flame. But beyond the walls lie war-torn deserts, ancient machines that should not still be alive, and enemies who believe the fire belongs to them. Among them is Kael-once a brother, now something far more dangerous. As the shadows of the old world awaken and the war for the last light begins, Arden must decide how far he is willing to go to protect humanity's final hope.
Because if the Flame falls.darkness will inherit the Earth. The Last Fire is an epic post-apocalyptic science-fantasy adventure about survival, betrayal, and the courage to carry hope through a dying world. Perfect for readers who love dark dystopian worlds, epic sci-fi fantasy, and stories where the fate of humanity rests on a single spark.
