Chronicles of the Undying

When a colossal eye peers through a crack in the ceiling of humanity's underground refuge, a young boy's fate is forever changed. A thousand years after civilization's fall, the remnants of mankind cling to survival in subterranean cities—starving, resource-depleted, and stripped of hope. But the creatures above, the Undying, are unkillable horrors that have claimed the surface world. As the boy confronts the truth behind these immortal beings, he must decide: will he join humanity's resignation, or become the spark that reignites their will to fight?
