A powerful druis with a broken spirit. A faithful tinker's unwavering love. And a determined, cunning queen driven by ruthless ambition.

Eight months ago, the man Avalína loved sacrificed his soul to save the Realms, a task that was supposed to have been hers. Now the most powerful druis in the world can barely hold her own spirit together.

When a mechanical butterfly lands on her finger and injects a lethal poison, it becomes clear that someone powerful wants her dead.

The search pulls Ava into places she never thought she would enter. In the frozen underworld of Tartarean, her fractured soul may find healing—but at a terrible price. And in the golden fields of Empyrean, Queen Liresí is devouring memories and building a chimera army poised to overtake Ava's realm.

With her soul splintering and magic faltering, Ava must navigate bargains, airship battles, and matters of the heart. All the while, Tobias, her lifelong friend who has loved her quietly since childhood, is done holding back—he's ready to love her in every way possible.

But the more fractured Ava's soul becomes, the less of her remains for him to reach, and the cost of saving the Realms may shatter what's left of her entirely.
