Fate cannot be broken - not even by the gods who serve it. Emory refuses to lose Romie again. Her friend's fate hangs in the balance as the monstrous Clover plans to use her as a sacrifice to steal power from the deity Atheia - and make himself into a proper god. To stop Clover, Emory needs the help of Atheia's dark counterpart, Sidraeus. Yet this enigmatic deity cannot be trusted, and if Emory is to ally with him, she must invoke an ancient magic to keep him tethered to her side. Meanwhile, in the divine workshop of the god of balance, Baz learns he has a role to play in the coming fight to save the crumbling worlds and their weakening magics. Yet all he can think of is Kai and the gruesome fate that awaits him at Clover's side - a fate, the god tells him, that is beyond even his reach. But Baz is determined to save Kai, even if he has to rewrite time itself. As chaos reigns and the tides of a corrupted magic threaten to consume all, Emory and Baz must contend with mercurial gods, vengeful deities, and those hell - bent on eradicating Eclipse magic to save the people they love - and write an ending to their stories that defies fate itself.
