A FATED LOVE. A COSTLY BETRAYAL.

Fia Riftborne thought joining the Sídhe Guard was the hardest choice she'd ever make. She was wrong.

Taken prisoner by those she swore to fight, Fia uncovers a devastating truth that upends everything she ever knew…about the Aossi…about Sídhe…about herself.

The only thing that is certain, is that Fia's growing powers are tied to the Isle's survival.

As war looms on two fronts, Fia must navigate a world of shadow magic and political upheaval. And, while tensions in Sídhe reach a breaking point, the Void that gave Fia her power is calling—but answering it means betraying everyone she left behind.

The Guard. Her friends. Laryk.

In a war where nothing is as it seems, choosing the wrong side could cost her everything, including the brooding commander whose darkness seems to call to her own.
