Levi Walker is pissed off. Seriously. After being the best demon hunter at Argos Inc. since forever, they want to screw him by not paying him for the jobs? Nope, Levi decides it’s time to go. Or at least it was until a hunt he’s on spins wildly out of control and causes a catastrophic loss…and everyone at Argos blames Levi. Now faced with being sued for the damage, Levi begins pursuing the evidence to clear his name. Jumping right into the fray, Levi soon finds himself in mortal danger. But he’s a fighter who'll battle until the end…which may come sooner rather than later, now that he’s met a beautiful and mysterious hunter at Argos and can barely keep his mind on the job. Will Levi stay alive long enough to find the proof to clear his name and leave Argos for good or will Cary prove to be the sexy and dangerous distraction that he just can't ignore? less

Not only did she get a job hunting demons, she also fell in love with the most badass hunter of them all. Oh and, if things weren't interesting enough, she managed to grab the top spot on the hit list of the biggest mercenary in Hell. Yeah, shit just got real.     Please note, Demon's Mark has been previously published in the Dark Legends boxed set. less
