Steelheart (Unabridged‪)‬

An android named Harley Doon finds himself caught in a battle between human and alien. It’s not his fight, but somebody has to save the world.

Years ago, when humans and androids crash landed onto the planet Zuul, whatever remained of their society quickly succumbed to the ravages of earthquakes and a never-ending winter from volcanic dust clouds. As humans and machines scavenged to stay alive, they also faced the Zid, an alien race that abhors all technology with religious fervor. Add to that the Mothri - giant, bug-like aliens with brilliant minds and their own nanotechnology - and it is no longer simply the planet’s geological upheaval that proves volatile.

War between the races looms. Will Doon, tired and reluctant, rise to lead the fight? Can humans harness technology to save the planet, itself, before the Zid arrive? And, what secrets does Doon carry inside of him that might help them all?
