In a world bound by prophecy and steel, the sacred sword of the Seraphim is governed by one rule: it may only be wielded by those who have never known love.

Kaileth has trained her whole life to fulfill this destiny. Fate has chosen her, sending her to carry the ancient sword into the heart of enemy territory to seal the gates of the Underworld forever. But when she meets Riven—a mysterious half-demon sworn to protect her—everything begins to unravel.

Riven is everything she's been told to fear. And everything her heart cannot resist.

As they travel through cursed landscapes, forgotten shrines, and the ruins of fallen heroes, Kaileth finds herself caught in an impossible dilemma: if she allows herself to love, the sword will shatter and the world will fall. But if she resists, the one person she loves most will die in her place.

In the final battle between duty and desire, Kaelith must make a choice no prophecy ever foresaw—and discover whether love is true weakness... or the weapon that changes everything.
