I’ll break you until the only escape you have is to end your own life,” he hissed, shoving her backward. “Undress, get on the bed, and be on all fours!” •••••••••••••• Benita was considered a burden and was never loved because she weighed a few pounds more than what was considered the perfect slender figure. Her younger sister, Nina, was the apple of everyone’s eye, the opposite of Benita. Nina had it all—a beautiful face, a slim body, and she was even dating Nathan, the soon-to-be Alpha. Everyone believed Nina would be his mate and the pack’s future Luna. But fate had other plans, as on the day of the mating ceremony, it wasn’t Nina but Benita who was revealed as Nathan’s mate. Nathan, furious and disgusted, was forced to accept her. Nina, devastated, fled that same night, only to fall from a cliff, her body lost, presumed dead. Nathan blamed Benita for ruining his perfect life and sought revenge. He turned his pain into a cruel revenge, subjecting her to a life of a slave. When Benita discovered she was pregnant, she fled, fearing Nathan would kill the child, unaware that Nathan’s feelings had started to change, though he would never admit it. Five years later, their paths crossed again. This time, Benita was no longer the broken girl the pack hated; she had made a name for herself as a renowned healer, and men now sought her out. But Nathan wasn’t about to lose her again. He’d let her slip through his fingers once, and this time, he would do anything to claim her. And as if fate hadn’t twisted enough, her sister, long thought dead, came back from the grave.
