The Blitz Extractor

In the shadow of Charlotte's stormproof walls, sixteen-year-old Mason lake thinks the Blitz is a completely destroyed graveyard.
He's about to find out just how wrong he is.
When masked soldiers rip his little sister from their home, Mason is given one way to earn her back: leave the "untouchable" city and venture into the ruins to scavenge whatever the city's elite will pay for.
But the Blitz is nothing like he's been told, and with every run, Mason discovers one horror after another.
Now the boy who only wanted his sister back must decide between becoming the monsters who took her or burning the whole system down.
