Shadowfire Oath

Magic has rules. Breaking them has consequences. Meet Aria Blackthorne-witch-for-hire, monster hunter, and occasional savior of magical strays. When she's not blasting demons with fire sigils, she's tracking down cursed artifacts for clients who can afford her steep rates. But when a mysterious vampire noble offers her a job that seems too good to be true-recovering a stolen relic known only as the Shadowfire Crown-Aria finds herself pulled into a deadly game of blood and sorcery.
The Crown isn't just powerful-it's the key to controlling the fragile balance between the human world and the hidden magical realm. And every faction-vampires, fae, witches, and worse-wants it for themselves. Now hunted by assassins, betrayed by allies, and haunted by her own past mistakes, Aria must decide who to trust and how far she's willing to go to protect a city on the brink of chaos. Explosive battles, razor-sharp wit, and a heroine who doesn't play by the rules-Shadowfire Oath is the first book in the Bloodbound Chronicles, a gripping urban fantasy adventure perfect for fans of Ilona Andrews, Kim Harrison, and Jim Butcher.
Magic has a price. Aria is about to pay it.
