“Wendy, are you absolutely sure you want to sign this document?” The Elder’s voice rang in my ears—cold, distant. “Once your bond with Alpha John is dissolved, you’ll lose everything tied to the Blackthorn Pack.” I gripped the pen so hard my knuckles turned white. “Yes. I’m sure.” But just as the tip touched the paper— BANG! The door was kicked open with a violent crash. Alpha John stormed in, eyes bloodshot, and wrapped his hand around my throat. “You dare?!” Blood slipped from the corner of my lips… but I laughed. Because I knew—he would never discover the truth. That his dear uncle, Alpha Vincent, was hiding in my closet at this very moment. And the fresh bite mark on my lower belly… still burned from last night. As if fate was mocking me, my sweet little sister Penny sent a message right then: “Sis, wanna know a secret? That miscarriage you had? John planned it. He made it happen.” Then the TV flickered to life with a breaking live broadcast— There she was, Penny, gently stroking her swollen belly as she smiled into the camera. “John and I are expecting our baby next month,” she announced proudly to the entire Pack. And Alpha John—my “husband”—stood beside her, lovingly kissing her forehead. Like I never existed. Like I wasn’t the Luna written in law. “Miranda,” my wolf snarled in my head, “Rip those traitors apart—now!” But I didn’t. I wiped the blood from my mouth, and dialed the number I hadn’t called in five long years. “Vincent,” I said calmly, “Come get me.”

My computer suddenly froze. The next second, my sister, Josie Bennett, appeared on the screen, covered in blood. Her face was white with terror as she screamed, “Nina, help me!” I looked at the pack of entities behind her, and my heart lurched. How had she gotten into a horror game? And an S-rank instance, no less. I had no time to think. I teleported in immediately. The moment I arrived, I saw a girl stomping on Josie, yanking her hair as she looked down at her with smug contempt. “You little brat. Still trying to call for help? Do you even know whose turf this is? Once you cross me, nobody can save you.” The players beside her quickly chimed in. “Exactly. Winnie is the woman of the top guy in this game. If you want to make it out alive, you’d better learn your place.” I stopped in my tracks, stunned. The top guy’s woman? Wasn’t I the final boss of this horror game?

On the night of my sister’s engagement party, my life officially crashes. Again. All because of one name on the invitation. Zachary de Sanctis. My sister’s fiancé. Fiona. My ex, the guy I punched in the face five years ago. Heir to the richest old-money family in Europe. And one tiny detail only God and I know: he’s the father of my twins. For the past five years, I’ve been hiding out in a little town in Oregon, working as the CEO of a IT firm while chasing two four-year-olds who look more like their father than me. Isaac and Isabella: two mini De Sanctis clones with the last name Gómez, razor-sharp mouths, brains that run too fast, and a talent for causing trouble exactly when I need peace. My family knows I came home pregnant and alone. They just never asked who the father is, and I never offered an answer. As far as they’re concerned, I’m still Arabella Gómez, the wild one who lost her way. I thought going to Fiona’s engagement party would just mean a few hours of fake laughing, then a quiet drive back to my glass-walled house in Oregon and two sets of blue eyes calling me Mommy. Until Zach walks into my parents’ living room holding Fiona’s hand… and his gaze stays on my face a little too long. He can’t find out about Isaac and Isabella. Fiona can’t find out her perfect fiancé was mine first. And my family can’t know what really happened five years ago. Hiding a scandal between two rich dynasties is one thing. Hiding two chaotic twins who are basically their father’s face copy-pasted? That’s the real nightmare.

In my previous life, Leon, the Alpha who was supposed to complete the marking ceremony with me, suddenly changed his chosen mate to my younger sister, Rose, on the very day of the ritual. Watching the two of them act intimately together, a wave of humiliation swept over me. Just as I was about to step forward and demand an explanation, the pack was suddenly attacked. All three of us died in the riot. When I opened my eyes again, I had returned to the day of the marking ceremony. This time, I chose to fulfill their wish. After leading the members to suppress the riot that would have happened in my previous life, I left the pack and entered human society. I thought I would never cross paths with them again in this lifetime. However, three years later, on the day of a birthday banquet, I unexpectedly met Rose and Leon again. Rose was leaning shyly into Leon’s arms, greeting me with a look of feigned surprise. “Claire! Why are you at such a grand banquet? “Didn’t you go to live in human society?” When I stayed silent, Rose mocked me with a laugh. “Could it be that you couldn’t survive in human society and now want to return to the pack?” Leon looked at me from the side, his expression filled with unconcealed disgust. “I would never agree to let you return to the pack even if you kneeled and begged me. “However, as my slave, you’d still be qualified. We could go back to how things were before.” I smiled faintly. I was here because my mate was the new Ultima of the wolf packs’ Alliance. And this exquisite birthday banquet was specially prepared for me.

She was supposed to be a business arrangement, nothing more. A wife on paper. A sacrifice to save a dying empire.

Humiliated, betrayed, and replaced by the one person she trusted most, her own sister. Milly walks away from the life she was forced to survive. Only to collide with Declan Laurent, a dangerously powerful man with his own secrets… and an unexpected proposal. A contract marriage. A mutual revenge. No love involved. At least, not at first. But when power, obsession, and buried truths begin to surface, Milly realizes escape was never the real danger… It was choosing the wrong man to help her burn everything down.

My younger sister was in a bad mood and went drinking at a bar, only to be dragged into a room by a few men. Not long after, she ended up pregnant. My husband, to protect her, actually suggested divorcing me so he could marry her instead. "Brooke only went to that bar because of me. I can't let people talk about her. Don't worry—once the baby is born and the paperwork is done, we'll remarry." I refused, but he heartlessly abandoned me, seven months pregnant, on the side of the highway. With my swollen belly, I walked for over an hour before finally making it off the road. There, I found my husband and my sister standing together, mocking me in my miserable state. "You wouldn't even help your own sister. Serves you right to suffer like this." "Noelle, don't be angry. I'm about to give birth, and Jensen only did it 'cause he was only worried about me." At that moment, I finally gave up completely. "Fine. Let's get divorced."
