The Rogue Horseman. A Guardians of Light Book, #2

Something is hunting the world's hope. Cities are starving. The land is dying. And in the shadows between famine and prophecy, an ancient evil has begun to stir-one that Heaven itself has feared for two thousand years. Cillian is no ordinary man. He was never meant to walk this path alone. But the ally fate hands him is nothing like what he expected-a warrior forged by loss, sharp-tongued and unbreakable, who trusts no one and fears even less.
Together, they will cross deserts older than memory and cities lost to time, chasing a trail written in blood and scripture. Every step brings them closer to the truth. Every truth comes at a cost. Not everything that walks beside you is what it seems. Not everyone you save is willing to be saved. And not every war is fought with swords. Some legends are prophecy. Some are warning. This one is both.
