In a world of suppressed magic, I'm an Unknown. Deadly power, little control. I'm only alive because I pay a Blood Sorcerer to keep me hidden. But when he comes to collect on the debt I can't pay, one of his goons slams me with a deadly curse. Suddenly, I'm out of options and out of time. When I'm given a rare chance to join the secretive Undercover Protectorate and train at their academy to become an investigator, I have a way to hunt the cure for the curse. They have resources I don't. Easy, since I'm broke. Seems like a good plan, right? At least, until they tell me Cade will be joining me on my hunt for the Blood Sorcerer. He's an actual Celtic war god--and the hottest guy I've ever seen. The catch? I can't let him know that I'm an Unknown, or I'm out on my ass and deader than Hades.
