Angel from the Rust

They say Earth was a place of wonders, where towers pierced the clouds, cities lit up the night, and flying machines streaked across the sky. It was magic. But the magic conjured the End War. Fire fell from the sky, and metal beasts leveled the cities.
That was six hundred years ago. Now the ruins of the Ancient world are buried or overgrown. And the technology of the past is feared as forbidden magic.
Corvala, a young musician on the run from the law, never intended on getting mixed up with history. But when a murderer falls from the heavens and sets himself up as a god, she's driven into the wilderness and discovers the secret of her bloodline: a code of immense power embedded in her DNA. The code could save thousands-or plunge her into madness.
To defeat the tyrannical false god, Corvala must do something more terrifying than confront the demons of Earth's history. She must confront her own.
