Eight years after a mysterious catastrophe wiped out his hometown, James is still haunted by the memory of a fire giant no one believes he saw. When a stranger appears with proof that gods and monsters from myth are walking the modern world, James is pulled into a hidden war between human "sequence-bearers" and mythic vessels capable of destroying entire cities. But as strange powers begin awakening inside him, the truth becomes even more terrifying: James may not be destined to stop the darkness-he may be becoming part of it.
