‎ ‎I died on Christmas Eve. ‎Poisoned by my sister… betrayed by the man I loved. ‎ ‎Death should have been my end. ‎Instead, it became my beginning. ‎ ‎When I wake up in a blood-soaked alley, a cold voice welcomes me to the “Demon Games" — a brutal survival arena where one hundred humans fight monstrous trials for a chance at rebirth. ‎ ‎The reward? ‎Ten years of life… and one impossible wish. ‎ ‎I am weak. ‎Near-blind. ‎And the easiest prey. ‎Which is why it makes no sense when “he" starts protecting me. ‎ ‎Tall. Masked. Dangerous. ‎His presence alone silences monsters… and makes my heart race for all the wrong reasons. ‎ ‎"Stay close," he whispers, his breath brushing my ear. ‎"Or I'll enjoy watching you beg." ‎They call him a demon. ‎A king. ‎A monster. ‎ ‎But when his hand grips my waist in the dark… ‎When his fingers tilt my chin up… ‎When his voice drops to a husky murmur. ‎"You're safer in my arms… don't make me prove it." ‎ ‎—I realize something far more dangerous. ‎I'm not just surviving the games anymore. ‎I'm becoming addicted to the man who could kill me. ‎ ‎Because the truth is… ‎The masked protector is the “Lycan King” — an overlord bound by rules that demand my death. ‎Yet every time we get too close… ‎Every time his control slips… ‎Every time his gaze lingers on my lips… ‎ ‎It feels less like protection… ‎And more like possession. ‎In a world where survival demands sacrifice and desire is a weakness… ‎I must choose— ‎Escape hell alone… ‎Or fall into the arms of the monster who wants to claim me. ‎ ‎

Noah, a broke, exhausted twenty two year old just trying to survive another bad year, who accidentally binds himself to Kael, a five hundred year old demon with too much attitude and not enough patience for the modern world. What begins as a desperate act quickly turns into an uneasy partnership, forcing Noah to navigate a hidden supernatural underbelly while juggling family obligations, poverty, and a demon who treats chaos like a hobby. As Kael adjusts to buses, phones, and indoor plumbing, it becomes clear he isn’t the monster Noah expected. Bound by rules neither fully understands, their pact draws attention from forces far older and far more dangerous than either of them. With power that always comes at a cost and a past that refuses to stay buried, Noah must decide how much of himself he’s willing to lose to survive and whether some bargains were never meant to be broken.

For hundreds of years, witches have been a sub species to the vampire race, used as slaves to do the bidding of the undead creatures; but when one witch catches the eye of the vampire Prince, all that could change. The very way the world was run will be erupted into chaos, throwing off the balance that so many had died to protect. When Luna is ripped from her bed in the night, she knew her time had come, that she would pay for her father’s mistake; her world would crumble around her when her mother is killed by the prince and she is taken into his custody. A slave. But that is what all witches should expect, what they are born into. It is the way it had been for hundreds of years, Vampires were the hierarchy of the world, though not that the mortals knew that; and perhaps they never would. The undead creatures liked to feast on the unknowing, on those they could control, dis-guarding the corpses when they had finished. Luna is taken to A city one hundred and seventy feet under the streets of Paris, there she would have to learn how to be a good slave as those around her all believed that witches and warlocks deserved to be there, that they were a lesser species and needed to be controlled. But when the young witch reveals her power, all that was about to change. A mind link had never been formed between a witch and a vampire before, no one thought it possible, but when Luna makes it into Silas’ mind something happens; something that would change the course of their destiny and the fate of all those around them. With rebellion and chaos only around the corner, how will anyone survive?
