Ximena Castellanos was supposed to be a ghost. In a world ruled by the ancient Alpha bloodlines of Spain, being born without the Shift meant being invisible. She was just the powerless daughter of the most feared Alpha in the country; overlooked, underestimated, and kept. But on her twenty-first birthday, a golden Mark burns into her skin, binding her soul to Bastián Valdemar, the ruthless Alpha who just crushed her pack into ruin. To her father, she is now a weapon. To Bastián, her blood makes her the ultimate enemy. To survive, Ximena fakes her death and infiltrates Bastián's pack under the false name Salomé. The plan is simple: hide in plain sight. Earn his trust. Then destroy him from within. But the Vínculo cannot be denied. As Bastián hunts relentlessly for the missing Castellanos heir, he finds himself dangerously obsessed with the sharp-tongued woman standing right in front of him. Every stolen touch threatens to expose her. Every shared breath pulls the trigger. He bullies her, tests her, tries to break her but she refuses to bend. When the truth finally drops, the blood spilled will either drown their world or forge an empire.

He rejected her because she did not shift at eighteen. In front of the pack, Alfred Edward called Arieth Caspian a witch, a stain on the alpha line, and a disgrace tied to an extinct bloodline. He thought humiliation would erase her. Instead, it made her dangerous. Now Arieth survives on grit, and a smile sharp enough to hide the fear underneath. But when a dark lycan alpha named Lucien Xander steps out of the shadows, the whole territory feels it. He is older, colder, and powerful enough to break men like Alfred without raising his voice. He does not pity Arieth. He challenges her, trains her, and watches her like he already knows she belongs to something far greater than the pack that rejected her. As black magic stirs in Arieth's blood and enemies close in from every side, she will have to decide whether she is the broken omega they mocked or the woman destined to burn their lies to the ground.
