Zeroth Law (Digitesque #1) by Guerric Haché

Autonomous machines polish the bones of a civilization slowly being swallowed by wilderness. Creatures not born of Earth inhabit the remote corners of the world. Humans live with legacies they don’t understand - old ruins, strange technological artifacts, incredible powers in their blood. There are other worlds alongside this one, and death is not what it once was. Isavel is ripped from a simple life into the heat of a conflict she doesn’t understand, and saddled with powers and expectations she doesn’t know how to handle. Lost in a storm, she hopes that by following the will of her gods, she might find purpose - and ultimately, peace. Ada took her own peaceful life and threw it out the window. Outcast for heresy against the scholarly dogma of her people, she decides the world needs to change, and she thinks she’s the one to do it. To her surprise, she happens to be living at a time of more wondrous and terrible change than she can imagine. These two young women must navigate a world that is is barely holding together, each only slowly becoming aware of the other’s existence and power. Each of them will have the chance to light a fire to change the world - but first, they must become the people they will need to be.

When a song is a weapon, who can wield it? Piper is a minstrel whose music incites forbidden magic. He lives in fear of being charged with heresy; the church uses the same power to crush offenders, without mercy or hope of redemption. His problems have cost him both the woman he loves and his growing career as a minstrel. Worse, he’s entangled in the politics of the capital, attracting the scrutiny of the priests. Terrified they’ll turn him into a mindless beast, he runs. Can he learn to control the magic, and use it to slice through centuries of the church’s lies? Or will he end up as the priests’ latest victim, all ability to feel hope, love, or even hate ripped from his mind? The Eternal Muse: Desecration is the First book in the Eternal Muse trilogy.
