Embers of Night: Red Horizon

Gavin DeMaze discovers every corner of the world- is coming for him. He and his brother Ryan become immersed in a struggle between two ancient and powerful factions. As a Deviant infestation threatens humanity- it's up to the DeMaze brothers to band together a broken legion of Paladins to bring order and peace to both the physical and spiritual worlds.

When both worlds fall to chaos, only the few have the power to survive, only the Paladins can push back the darkness. To survive here, you'll need more than cunning, you'll need more than guns. Shadows move in the night, and corpses of long dead monsters rise to transcend the confines of time and biology... even bullets can't stop them.
