Alexander lives his life for two reasons: to protect his mother and keep his one-sided love for Katharine hidden. He is a servant, incapable of reaching the top of the social ladder without help. Chances like that come at a cost, and he is more than willing to pay for it.
All does not go according to plan. The woman he loves marries another, the man who tried to kill him becomes his rival, and the fate of his mother changes for the worst. Alexander knows one thing for certain. He cannot turn the time back, just as he cannot become human again.
