The horn was a summons, and everything answered it.
The battle of Dagon Hills: a stubborn little town, a farmer with a pistol his grandfather bought for a war that never came, and Mary — learning in the worst possible classroom that her power isn't armor. It's faith. And faith can be broken.
Beaten, hunted by a machine that hears something inside her no one can explain, Mary falls out of the fight and into somewhere else entirely — and watches, from inside the blue, as something new enters the war: a streak of pure white fire that moves the way joy moves, and takes the king apart.
Then the diamond dust clears, and a barefoot girl skips down the wreckage of the thing that broke her, and says the words that change everything: "There hasn't been anyone new for two hundred years."
Her name is Hannah. She has been waiting a very long time. And she knows what the power in Mary's blood is actually called.
