Traces of Sulfur by Madeline Freeman
I’m not who they think I am. If they learn the truth, I’ll pay with my life. Blakethorne Academy is the premier training ground for warriors. Every person here will one day be a member of the angelic Guard. As a demon, it’s the last place I should ever step foot. But I couldn’t exactly say no when they handed me an engraved invitation to attend. Access like this doesn’t come around every day. My people are in peril, and walking among these angels could give me what I need to save them. I just need to keep my true identity a secret. But that gets harder by the day when the lead Keeper, Nate Kouri, sets my heart galloping every time he draws near. Getting close to him is dangerous, but I’ve never been one to turn down playing with fire. They think I’m a Blade Keeper—one of five elite warriors destined to defeat whatever evil rises. If they learn I’m a demon, I’ll pay with my life. My name is Eden Everdell. Saving my people has always been my mission, but ensuring the survival of my brethren might destroy me.
