Ashes Of Tomorrow

For forty years, the survivors of Vault 112 have hidden from the sky. Now, the life-support systems are failing, and the "Bunker Born", a generation raised on recycled air and LED light, must face the world that broke their ancestors. Sent on a suicide mission to retrieve a legendary atmospheric core from the ruins of a Tier-1 city, three unlikely leaders, Elara, Kael, and Miri, step into a landscape they only know from books, but the wasteland isn't dead; it has evolved.
From the neon-choked "Gray Forest" to the predatory scavengers of the Iron Harvest, every mile is a battle for air, blood, and morality. Guided by a mysterious radio signal from a ghost station, the Alpha Team must navigate a brutal new economy where salt is currency, and survival is a sin. As their oxygen tanks tick toward zero, they realize they aren't just fighting to save their bunker, they're fighting to decide if humanity deserves a tomorrow at all.
A gritty, high-stakes journey through a beautifully broken world.
