“I will make you suffer, mate. I’ll break you until the only escape you have is to end your own life,” he hissed, shoving her backward. “Undress, get on the bed, and be on all fours!” •••••••••••••• Benita was considered a burden and was never loved because she weighed a few pounds more than what was considered the perfect slender figure. Her younger sister, Nina, was the apple of everyone’s eye, the opposite of Benita. Nina had it all—a beautiful face, a slim body, and she was even dating Nathan, the soon-to-be Alpha. Everyone believed Nina would be his mate and the pack’s future Luna. But fate had other plans, as on the day of the mating ceremony, it wasn’t Nina but Benita who was revealed as Nathan’s mate. Nathan, furious and disgusted, was forced to accept her. Nina, devastated, fled that same night, only to fall from a cliff, her body lost, presumed dead. Nathan blamed Benita for ruining his perfect life and sought revenge. He turned his pain into a cruel revenge, subjecting her to a life of a slave. When Benita discovered she was pregnant, she fled, fearing Nathan would kill the child, unaware that Nathan’s feelings had started to change, though he would never admit it. Five years later, their paths crossed again. This time, Benita was no longer the broken girl the pack hated; she had made a name for herself as a renowned healer, and men now sought her out. But Nathan wasn’t about to lose her again. He’d let her slip through his fingers once, and this time, he would do anything to claim her. And as if fate hadn’t twisted enough, her sister, long thought dead, came back from the grave.

My parents suddenly told me that we were living in a novel. I was the frail and favored younger brother destined to get into college, marry my childhood sweetheart, and live an easy life. My older brother, Daniel Luther, on the other hand, was the expendable one. He was destined to fail his SAT and be beaten to death. My parents said that if they wanted to save him, they had to make sure he got into college. They did everything they could to help him, but he still failed his SAT. Meanwhile, I got into the same college as my childhood sweetheart, Priscilla Grimmie, through my own hard work. That night, my parents snatched my college acceptance letter and locked me in a cellar under the backyard. "Let your brother take your place and go to college first. You can retake your exams next year." My foot slipped, and I hit my head hard against a canning jar. Warm blood trickled down my neck. I shouted, "Mom, it hurts!" She didn't even turn around. "Caleb, stop it! Your brother is one step away from his dreams!" Their footsteps gradually faded. I slowly closed my eyes. The next time I opened my eyes, I was already floating in midair.

“Who would have thought goody two shoes Tatiana Olivera is a nasty sl*t who fantasies about f*ck*ng her step brother?” Hasan continues his teasing. He inserts in middle finger in my mouth and I greedily s*ck on it, picturing it to be his c*ck. Hasan’s mouth parts open, his brows cresting as he watches me s*ck his middle finger like a kid sucking on a candy cane. I frowned when he pulled out his middle finger. He grabs my chin with a fierceness that sent me on edge. “Open your mouth.” He orders and I obey. He takes in a deep breath as though calming himself and before I knew it, hot liquid drops into my mouth. Did.. did he just spit in my mouth? It tastes divine. It tastes like him. And I want more. “Swallow.” I meet his gaze as I gulp down his saliva. A proud smile appears on his face. “There’s my good little sl*t.” ***** I hate Hasan Olivera. I can’t stand him. The way he walks into the room like he owns the place, the smug smirk that says he already knows what I am thinking. He’s insufferably cocky, sharp-tongued, insanely hot and fully aware of it. And those eyes? Dark, knowing, endlessly amused by the fact that, no matter how much I pretend otherwise, I’m completely drawn to him. I want him to f*ck me. I want him to claim me. I want him to be mine because I belong to him. But he's my step brother. And I hate my step brother. -------

"Killing you would be a mercy. And mercy is not what this family gives." Sold to pay her father's debt. Married to the youngest son of the deadliest mafia family in Spain. Widowed before the wedding night was over. Now Alondra Reyes-Salamanca belongs to the older brother, the man who watched her try to run and pulled her back into the dark. Dante Vidal-Montenegro has sworn to make her pay for a murder she did not commit. But someone in this house is hiding the truth. Someone wanted Iker dead. And the more Dante hurts her, the more he begins to suspect that the woman trembling in his bed every night may be the only innocent thing left in his entire bloodline. Enemies to lovers. Mafia kings to confessions in the dark. A debt paid in blood, a bride paid in pain, and a love story written in everything they were never supposed to feel.

She came to kill him. He was supposed to be her enemy. But the bond they built on lies might be the only real thing either of them has ever had. Zara Merrick has one mission: seduce the Alpha who murdered her sister, earn his trust, and drive a silver blade through his heart. She endures an agonizing ritual that rewires her very biology — altering her scent, implanting false recognition signals, creating an artificial mate bond designed to make the most powerful Alpha in the region believe she is his fated one. She walks into his territory like a weapon wearing a woman's face, and it works perfectly. Ryker Bloodmoon falls for it completely. Or so she thinks. Because Ryker has secrets too — secrets about the night Mia Merrick died, about what her sister really was, and about the truth The Covenant has been hiding from Zara for five years. And when his Beta runs her blood and the lie unravels, Ryker doesn't kill her. He keeps her. Now Zara is a prisoner in the fortress she came to destroy, hunted by the organization that sent her, and haunted by the possibility that everything she believed about her sister — about werewolves, about the war she dedicated her life to — was a carefully constructed lie. Worse, the fake mate bond is dissolving. And what's replacing it feels terrifyingly real.

My younger sister, Noelle Lynch's 18th birthday wish is to personally give me the wedding bouquet at my wedding. That's why throughout the five years of Noelle getting tormented by polio, the sentence that I utter to my fiance, Jeremy Morgan, the most is, "Wait a little longer." I want to wait till Noelle is fully recovered and can give me the wedding bouquet. Only when that time comes will the wedding be held. At first, Jeremy keeps arguing with me over this matter. "You're marrying me, not Noelle! Is it that important for her to attend our wedding? My mom really wants us to have a child! If we're not getting married by this year, then we might as well break up!" Things between us have soured since that day. When Noelle finally recovers from polio at the end of the year and wins the pageant as Miss Global Winner, I specifically give myself a long vacation. Then, I secretly contact the wedding planning company in hopes of moving the wedding date forward. But the staff member asks me in shock, "Didn't Mr. Morgan hold his wedding last month?" She even digs out the backup video from the wedding on her computer. In the video, Jeremy can be seen wearing a white suit. With red-rimmed eyes, he slides a ring onto the bride's finger. Shockingly enough, this bride is Noelle, the very same person who keeps claiming that I'm her salvation. I feel as though I've plunged into an icy abyss. Subconsciously, I log into Noelle's social media account. The first thing I see is a barrage of messages from Jeremy. "Honey, I already told her that I'd go on a business trip for a month. We'll meet up at the airport right on time. "By the way, remember to bring the black lace stockings that I've given you. I'm already looking forward to seeing you wearing them…" I clutch my phone tightly at the sight of the messages. Then, I hail a cab and rush to the airport immediately.
