Will love be enough to bind these two broken souls?

Reunited after years of separation, Kyrra and Arsenault long for a peaceful life together. But the magic keeping Kyrra alive is also tearing her apart. When a mysterious piece of ancient metal falls into Arsenault's hands, he gambles that it will prove to be Kyrra's salvation despite the secrets from his past it threatens to reveal.

Kyrra is willing to sacrifice everything to free Arsenault from the vengeful god who haunts him, even if it means embracing the magic killing her. But Liera is on the brink of war again, and an unlikely alliance with her greatest enemy may be the only way to save it from destruction.

With their love tested by powerful forces, Kyrra and Arsenault face a heart-breaking decision between their own happiness and the greater good. As the dark truth begins to unravel, can their promise hold—or will they find it was a fool's promise after all?
