My entire family could hear my thoughts. In my previous life, I was switched at birth with Victoria Harrington. I was reunited with my family 18 years later. It was the early 1920s, when owning a bicycle or a radio was still rare for most families. I had always dreamed of having one of those precious things. However, after I came home, Victoria would constantly brag right in front of me. "Mom told me that I'm the only one who deserves this fancy watch," she said with a sweet smile. "And look at this gorgeous bicycle Dad got me for my birthday! Oh, and when I mentioned wanting a radio, Daniel bought it for me immediately." Then came the real knife twist. "I know you're their biological daughter, Bernice, but let's be honest. When it comes to love, I'm their real daughter. Daniel definitely prefers me as his little sister too." Her words ate at me. I could not stop the bitter thoughts that flooded my mind about my parents and brother. The problem was that my family could hear every single one of those thoughts. Slowly, they began to resent me. Eventually, they threw me out into the cold, and I died alone in the winter streets while Victoria lived happily within the warmth of their love. When I opened my eyes again, I realized that I had been reborn. As I watched Victoria putting on her usual show, my thoughts took a delicious turn. 'Victoria thinks that Mom is such a cheapskate for only buying her a cheap watch instead of something expensive. She even calls Dad stingy behind his back because he didn't get her a pricier bicycle.' 'And she constantly complains about how ugly and crude Daniel is, saying that he embarrasses her. I wonder if I should share these thoughts with my family?'

I was the daughter of the Ashford Pack Alpha — the most beautiful she-wolf in the entire southern territory. Alphas lined up to pursue me, and I couldn't be bothered to give any of them a second glance. Until my best friend dared me: "Sera, I've got a bet for you. Think you can make my brother Kieran fall for you? Win, and I'll give you my mother's healing moonstone necklace. Lose, and you hand over that limited-edition sports car you love so much." Countless beautiful she-wolves had tried to get into his bed. Every last one of them had been turned away cold. The very first night after I took the bet, I saved Kieran from a silver poisoning, and spent the rest of that night tangled up with him while he burned through his heat. For the two years that followed, he grew more and more obsessed with me. On the long conference table in the pack meeting room, he pinned me down against the papers. In every room of his private estate, we left traces of ourselves behind. I gradually fell in love with him during countless intimate moments. Until the night only to overhear his conversation with the pack elder. "Alpha, it's time to announce who will be Luna." The Elder's voice was low and deliberate. "Miss Seraphina has been by your side for two years now. According to pack tradition—" "Enough." Kieran cut him off. "She and I were just having fun." The Elder was quiet for a moment. "And your first love? When you two separated, she asked for two years apart to try other partners. Those two years are up now. Isn't it time for her to come back?" "Yes." Warmth finally crept into Kieran's voice. "It's time for her to come back." That was when I realized — his so-called true love was my half-sister. The person I hated most in the world. For two years, I had been just his experiment while he "tried someone else". I turned and walked away without a second thought. But this powerful Alpha went mad — tearing through the entire wolf world searching for me.

My life was simple. Boring, even. That changed the day my mother married the richest Alpha in the pack. I fell for his son, my stepbrother Felix Dimitri is damn hot, infuriating, and impossible to ignore. He is my stepbrother by marriage, my fated mate by the Moon Goddess’s cruel design, and the one man I should never want. His storm-dark eyes ignite something inside me I cannot control. Every glance tightens the bond between us. Every accidental touch feels dangerous. I know he feels it too, even as we both pretend we can outrun fate. School, family, friendships. Nothing stays untouched when desire cuts this deep. Staying away from Felix is impossible. Giving in could destroy everything around us. But resisting him? That may be even harder.

His hands slid up my thighs, in a slow and deliberate manner, and my breath hitched. “What if…” I gasped as his fingers tightened possessively. “What if my mother finds out?” He didn’t answer with words. Instead, he captured my lips in a searing kiss that swallowed my protests and set my entire body aflame. His mouth moved against mine with a hunger that said he didn’t care about consequences, didn’t care about anything except this….except us. When he finally pulled back, his eyes were dark with desire, his voice a low rumble against my skin. “Then let her.” ~~~ When fate deals the cruelest hand, desire doesn’t play fair Belle Westwood never expected her fresh start to come with a mate bond—especially not to the one man she absolutely cannot have. He’s powerful, commanding, and everything her wolf craves. He’s also her mother’s husband. One stolen kiss changes everything. Now, caught between duty and an attraction that threatens to consume them both, Belle must decide walk away from her fated mate, or risk destroying everyone she loves for a chance at the one thing she’s never had—true love. But when her past comes back to haunt her and enemies close in, Belle realizes that sometimes the most dangerous thing isn’t the secret you’re keeping… it’s the one you can’t resist.

My sister pushes her daughter at a murderer so she can win the prize in a photography competition. After this, she even uses the incident and my name to extort the victim to pay an astronomical sum as compensation. The victim stabs me to death in a fit of rage. When my son, who is brought up by me, learns the truth, he doesn't seek justice for me. Instead, he scatters my ashes in the sea and says, "My mother told me that I would've been the happiest child in the world if not for you taking the wrong child home back then." When I open my eyes again, I'm taken back to when my daughter was five years old. I have a month until her death. This time, I'm going to protect my child to the best of my abilities. I won't bother about an ingrate anymore.

On our wedding night, my husband Grayson's sister-in-law, Scarlette, stumbled drunkenly into our bridal suite and threw her arms around him, refusing to let go. "Kayla, my husband died young, and I really just want a child. Please, lend him to me for one night," she cried through her tears, shoving a toy into my hand. "I promise I'll return him tomorrow. And if you get lonely… you can use this to comfort yourself." I stood there, dumbfounded, my gaze shifting in confusion to Grayson, who was already helping Scarlette steady herself. "You're really going to sleep with her?" He avoided my eyes, his tone strangely urgent. "Don't overthink it. She's drunk and talking nonsense. I'll take her back to her room to rest." As he started to leave with her, I stepped in front of them, blocking their way. "Grayson, it's our wedding night tonight. Are you seriously going to walk out with her?" His expression darkened as he pushed me aside. "You're my wife now—try to be more sensible. Don't get jealous over something so trivial." Then, carefully, he guided her out of the room. I wanted to run after him and stop them, but when I saw the deep concern in his eyes as he looked at her, the truth finally hit me. The love this man had for me was no longer mine alone. And if that was the case, why should I cling to a marriage that had already soured? I might as well walk away with my head held high.

"You remember how good it felt," he murmured, his lips grazing my ear. "Don’t pretend you’ve forgotten what it’s like when I make you beg." One night. One mistake.

He dares her to fall. But Ethan’s secrets could destroy everything — including her. She knows she's falling hard, but Ethan has plans of his own...
