My adopted sister won the Elixir Challenge by stealing my potion. To her shock, she was informed that the event was a selection event for the future wife of the Serpentkins' future head—the same heir who was infamously impotent, barbaric, and hideous. When the Serpentkins sent over a proposal letter, demanding her hand in marriage, my fiance panicked and promptly took my adopted sister away for a quick marriage and even consummated. Once the deed was done, she returned triumphantly, showing off the mark on her lower back. "Well, what are you going to do now, Winnie?" she gloated. "Your fiance is mine now, and you'll be twenty-five in three days. If no one comes to pick you up, you'll just be dumped into the hands of some wife-beating Rogue who is ageing and unwanted…" Actually, she was wrong—I had a choice. I went to the parlor where my parents—who were busy fixing the mess my adopted sister made—were, announcing, "If she refuses to marry the future head of the Serpentkins, I will!"

"Selene, your bloodline is too lowly. You don't deserve to be a Luna! You must let your Alpha mark his sister-in-law!" My mother-in-law despises me because I'm a lowly Omega. When my mate's brother dies in an accident, my mother-in-law wants me to allow my mate, Eugene Latham, to have pups with his sister-in-law, Kristy Unwin, because of her superior bloodline. Otherwise, Eugene will lose his right to become Alpha! Eugene wraps his arms around me tenderly and says, "You're the only one in my heart, but you need to understand that the pack can't go without an Alpha. I'll announce to everyone that you're my Luna once Kristy's pregnant and I become Alpha, okay?" I love him deeply, so I believe him. However, when Eugene goes from sleeping with Kristy once a month to sleeping with me once a month, I realize he's no longer a mate who belonged to me alone. When Kristy announces that she's pregnant and that she and Eugene are going to get married, I'm the only one who's kept in the dark. My heart shatters into pieces when I see the glimmering Luna's ring on her finger. If this is what Eugene wants, I'll fake my death and leave him. I won't ever return.
