Every king before him killed a god. Keiran may be the first to refuse. Every five hundred years, the sky cracks open and the gods fall like rain, bleeding gold that burns the green of the world to desert. And every five hundred years, the king of House Elian hunts one of them down, chains it, and eats its heart. It is the oldest secret of his bloodline, and the reason his throne is called Undying. Keiran Noxus Umbron, Prince of House Elian, never wanted to live forever. His father did, for four hundred and ninety years, before he ended his own life and left behind a warning: a long life is a curse disguised as a blessing. Now the Divine Chasm is opening, and Keiran must kill a god to earn the crown. But in the burning dark where the gods have fallen, he finds something that was never meant to be there: a starlit maiden, powerless and alone, lost in a war that was never hers. Keiran swears to help her return to the sky. The more he learns of her, the less he wants to kill anyone, god or otherwise. But the Chasm will not stay open forever, the crown demands a heart, and no king has ever failed. To keep his promise, he must betray the legacy of his house. To keep his throne, he must betray her.
