Twice Rejected Omega, The Alpha's Regret

Hope, a normal human girl, had a weird dream at the night she turned eighteen, where a masked man came to her bedroom and took her innocent.
What was more disbelieving, the next morning her grandfather let her know that she would be married to someone who she had never met.
Before Hope could figure this out, an evil trouble was approaching her. The masked man appeared again, domineeringly claiming that she was his mate, and she was destined to give him a baby.
