The Gene Thieves - Gleaming Walls of Ash, #1

The Reclaimers rose when the world fell, guarding what was left of humanity from the virus known as the Rust. But after decades of neglect, now is their time to rise again. The night Holt killed his father is the night his world changed forever. Driven into the unforgiving wastes he must fend for himself, scavenging an existence in the desert of zone Epsilon. All in service to Triumph, the technological utopia, and one of the few remaining human cities on Earth.
When a chance encounter with a legendary nightmare puts him on a path through the city, new friends and enemies are made, joining them in a quest that may just cure the world of the virus that nearly destroyed it... or condemn them all to a fate worse than death. The Gene Thieves is the exciting beginning to the Gleaming Walls of Ash series by Joshua Dorne. A look into life after the world collapsed, and the beginning of a brand new age.
