"Cade Halloway is a hunter, raised by the Order of the Covenant--a cult built on blood, sacrifice, and power. He tracks and eliminates the powerful and corrupt. A predator disguised as a savior, but he's not here to save the innocent. He's here to rip apart the monsters who hide in plain sight. For years, he has been their weapon. Until he discovered the truth...his sister Callisto is slated to be their next offering. Callisto Halloway was supposed to die for the Order, but her brother has other plans. While in hiding, unable to help or fight, she spends her time trying to control the power she was born with, the power that the Order will kill for. But independence comes at a price, and her uncontrolled power summons a demon far more dangerous than the Order. One that wants more than her body or her soul. Now, on the run from the Order, Cade's only purpose is to save his sister. But Callisto's power has consequences. There's now an unseen force--a spectral presence--following Cade he can't explain andcan't escape. A presence that breaks down all of his defenses, and tears down walls even he didn't know he had built, as he finds himself drawn to it in mind, spirit, and body. And it may be the only thing that can save him and Callisto. You. Are you sure you want to be haunted?"--
