Ten years after nuclear fire and a mutagenic virus ended the world, Leo Weston-born the day it all collapsed-finds himself enslaved by an alien race that harvests children and repurposes mutant survivors. Alongside Siena, a once-feral girl whose humanity was restored by alien serum, Leo is forced into a galaxy-spanning army of orphans sent to burn broken worlds.
But as their missions pile up and the truth of their captors is revealed, Leo and Siena rebel, risking everything to return to Earth. What they find defies all logic: the planet reborn into paradise. Lush. Alive. Perfect.
Because that's what the invaders do. They cleanse what's broken. Rebuild for the future. Not for the living, but for those they choose to remain.
Now the only ones to return, Leo and Siena stand at the edge of a new beginning. But peace is fleeting. A darker force-older than the Architects-awakens in the far corners of the galaxy. One that feeds not on death, but on forgetting.
To stop it, Leo must become more than human. More than light. He must become the flame that remembers.
