A lonely twelve-year-old girl has spent her life breaking every rule except one: never enter the forest.
Then a vanishing fairy appears in her grandmother’s mansion, begging for help. Minutes later, creatures of living starfire tear through her home, reducing marble, gardens, and everyone she loves to ash. With nowhere left to run, she follows him into the forbidden woods—and into a hidden world where fairies are not legends, but soldiers in an ancient war between celestial powers.
The Summer Court is dying. The Star Demons are coming. And the only power strong enough to stop them belongs to a wounded fairy king who can no longer wield it.
To survive, the girl must accept the King’s Blessing: a power that can command the living world itself. But taking it will make her immortal, trap her forever in the body of a child, and bind her to a war she never asked to fight.
If she refuses, the world burns.
If she accepts, she may never be free again.
