Alpha's caged love

On her 18th birthday, Selena was sold by her father to an elderly Alpha who just desired a breeder. She was the bastard child who was despised by all. In an ideal world, her envious stepmother would have killed her, but because of her Alpha blood, her father allowed her to live. Her life suddenly took a turn for the worst after five years of agony with her forced mate. Her pack was taken over by the vicious Alpha Cayden, who also killed her mate. Selena had given up on life and was wishing for death, but Cayden wouldn't let it. He desired to use her as a plaything and a toy. Something to demonstrate to others his ability to seize and make use of anyone's mate. Was there more to his act? would he use her until she lost the will to live? Love or revenge which one would win?
