“How sore are you?” His unexpected presence made me jump in fright. “Your Majesty?” I spun around to see him sitting on the bed I had been staring at earlier. “Come here.” He didn’t repeat the question. Did I mishear? “Your Grace, if you’ll just let me finish cleaning up this area—” I rushed out, suddenly confused and nervous about why he’d want me to come closer. “How about you abandon that and come sit, Cassia. Now.” His tone was firm yet soft. I almost gasped when he raised his eyebrows and patted his left thigh. I gulped hard and took tentative steps toward him…. In a world where medieval and modern collide, werewolves, vampires, and hybrids rule while humans live in fear, their lives not fully belonging to themselves. Cassia is one of the unfortunate souls sold by her aunt to the hybrid palace, a place desperately in need of new servants. Living under the roof of the infamous Hybrid King, who harbors a deep-seated hatred for humans—especially due to their role in the brutal attack that harmed his mother—her fate becomes dangerously intertwined with his. As she navigates the treacherous palace with survival on her mind, she becomes entangled with the King, who fights against an undeniable attraction to the very human he despises.

Some chains are made of iron, others are forged by fate. Edrian Lorne has never dreamed of freedom. Born a slave, trained to obey, and scarred by a master’s cruelty, he has learned one truth: hope is dangerous, but when war tears his world apart, he finds himself standing before the Crown Prince of DarkMoonCrest… and the impossible happened when their eyes met, and the mate bond roared to life. Prince Xander Veyrion has spent his life pursuing one thing, the throne. The bond to a slave is a threat to everything he has built, to every alliance he needs. Yet denying the pull between them proves harder than ruling a kingdom cursed to rot without a noble-born mate. In the shadows of court intrigue, deadly magic, and whispers of rebellion, the bond between Edrian and Xander burns hotter with each stolen glance and forbidden touch. But when betrayal strikes and a killing curse forces their hands, they must decide, cling to ambition and lose each other, or defy the kingdom and claim a love that could bring an empire to its knees. A slave with no hope. A prince with everything to lose. And a bond that could change the fate of a kingdom.

King Lucien Draven rules the United Packs with cold iron strength. He has crushed every rebellion and refused every mating alliance. Lycan law demands a king produce heirs with a royal female or face challenge to his throne. Male omegas are disposable tributes, never equals. Then Caelan Ashford arrives as tribute from a fading noble pack. The quiet, scarred omega expects death in the royal palace. Instead, his scent ignites the ancient mate bond the instant their eyes meet. The pull is raw, immediate, and utterly forbidden. Lucien fights the bond with ruthless control. He confines Caelan to the lower halls, assigns him to brutal training, and buries desire beneath duty. But every stolen glance and accidental brush erodes his restraint. The bond grows stronger, darker, impossible to ignore. Caelan hides a deadly secret: royal blood from the dynasty Lucien’s ancestors destroyed. His silver collar dulls his true scent, yet it cannot hide him from the king or from Prince Rowan Draven, Lucien’s charismatic and dangerous younger brother. Rowan sees Caelan as both prize and weapon. He offers protection and power in exchange for loyalty, circling like a predator while court intrigue thickens with assassination plots and rising rebellion. Torn between throne and heart, Lucien must decide how much he will risk for his forbidden mate. Caelan, trapped between two lethal alphas, navigates betrayal, awakening power, and a bond that could destroy the kingdom or remake it. In a slow-burning dance of denial and surrender, where every touch courts war and every refusal cuts deeper, one forbidden connection threatens an empire and two wounded souls who were never meant to find each other.
