Ancient magic once poisoned the world, and though there was a valiant effort by heroes brave enough to try and stop its reign, it wasn't enough. The world as it existed was plunged into eternal darkness. Those who failed to stop the blight were punished, and what was left of the war-stricken world was forced to pick up the pieces and continue on.
Centuries later, Felicity Belflame isn't a hero, far from it. She's a criminal forced to embrace the darkness after the light in her life turned its back on her. As a witch, she's deemed not significant for anything worthy and in a reckless attempt to change her fate, she stumbles into a political world far more vicious than she could've imagined. King Asche is a wartime hero loved by all for his effort in saving the last city from plunging into complete darkness. However, he has spent the last few centuries stewing in bitterness and resentment for witches after being betrayed by the love of his life when he needed her most. When a powerful witch falls into his lap after centuries of avoiding them, he knows better than to believe in coincidence. Fate, it turns out, has plans for these two. A powerful magical force can only stay dormant for so long, and it will take Felicity and Asche to work as a team to stop the newest wave of destruction from taking out their world completely.
