Beta girl Susie was adopted by the Crawford family for her rare blood and became the "blood servant" of their daughter Isabella—then was used by her stepsister Dorothy. When Dorothy lured her again, Isabella caught them, and Dorothy accused Susie of drugging her. Susie was exiled to a rigid aristocratic academy. On day one, she stopped basketball captain Brianna from bullying a freshman—and formed empathic bonds with all three team stars: Brianna, heiress to the richest family; Paige, the dean's daughter; and Rebecca, a mob princess. The four became roommates by accident, and Brianna, losing control of her pheromones, kissed Susie. Susie's prophetic dream revealed: due to a genetic conflict, she must find her destined Alpha and complete the mark within a month—or both will die. She resisted love but was pulled into a vortex with three Alpha queens: gentle Paige, dangerous Rebecca, and arrogant Brianna, who kept saving her. Dorothy escalated her persecution; Paige's admirer and Isabella also schemed. When Brianna's pheromones spiraled during her susceptible period, Susie risked her life to save her—and they confessed their feelings, breaking the curse with the mark. But Brianna, believing Susie saw her only as a "life-support tool," pushed her away. Susie discovered her birthmark hid the truth of her origins—and her blood was linked to Brianna's disorder. Before she could reveal it, Dorothy kidnapped her to harvest her blood, and Brianna was ambushed and left near death. Can Susie turn the tide? Can they clear the misunderstanding?
