Gog

In the swampy city of Shamgar, a port that doubles as a pirate hideout, a ruler named Gog holds power. He is the eldest son of a fallen angel and has a gift for glimpsing fragments of what is yet to come. When Gog learns that a man called Lod has cured a leper in the name of God, he sends his followers after the healed man. Meanwhile Lod is locked in the cellars beneath a fearsome Oracle, and the healed leper races to free him. The story follows an evil firstborn and the ordinary people who dare to stand against him at the heart of his stronghold, in the years before the seas swallowed the world that existed before the great flood.
