Herald by Rob J Hayes

A thousand years ago, humanity's greatest heroes killed God. Across the land of Helesia, the iron grasp of the Godless Kings is failing. Demons stalk the deep forests, monsters break free of their prisons beneath the World Vein, and terrors of the old world rise again. Deep in the wintry village of Riverden, Renira Washer lives the dreary life of a laundry girl, dreaming of excitement and adventure. But in her blood, hides a secret: the angels are not all gone. When a stranger from her mother's past appears with a dire warning, Renira's peaceful life is shattered and she's thrown headfirst into a millennia old war between Heaven and earth. Only the Herald can ring in the Fifth Age. Only the Herald can bring the God back to life. History is written in blood. The future is forged in holy fire.
