In the gray, rain-slicked streets of the Ota ward, seventeen-year-old Ren is a "ghost"—a boy who has learned to move silently to avoid the violence of his alcoholic father and the cruelty of school bullies.
Instead of an end, Ren finds a terrifying new beginning.
Joined by Lyra, a playful weaver of energy, and Vex, a disciplined tactician, Ren must navigate a world that expects him to be a king while he still feels like a broken kid from the slums. As the Sun Gods send their elite Paladins and monstrous Warden Beasts to snuff out the "Void" they cannot control, Ren must battle not only the divine tyrants but also the traumatizing echoes of his past.

To find the Celestial Sea and honor the promises of his old life, Ren must learn to master the starlight in his veins—or let it consume everything he is trying to protect.
