"Take off your ring." His command settled deep in my bones. I shouldn’t be doing this. And yet… I slid the ring off my finger. He stood on the other side of the room, his face hidden in shadows, but I felt him—his presence wrapping around me like a dark temptation. "Take off your clothes." I obeyed, my fingers hesitating at the waistband of my underwear. "I didn’t tell you to touch that." So I stood there—shoes on, pants still clinging to my hips—while my engagement party continued just down the hall. His gaze burned through me, drinking me in. "God, Butterfly." His voice was a tortured whisper, and I ached to comfort him. "Crawl to me." The words settled over me like silk and steel. Slowly, on all fours, I obeyed… --- Alessandra has always been the family push over even when her father forces her into a marriage.

"Let's be clear. While I stay here, no kissing, no hugging," Aiden Anderson said without breaking his gaze at Jessamine, his best friend since third grade. "You're my best friend... You're like a sister to me and my only family. I don't want to be reckless and lose you in the end." "I was only teasing you, Aiden. I'm not losing you as well. You're the only man I trust besides my father," Jessamine assured him. Jessamine turned her back on him, fighting the tears, unsure why her heart was disappointed. A part of her brain said she would rather die with heartache than admit to him that she wished there was more to their friendship, but her heart screamed something else. She wanted to be reckless with him and gave her heart the freedom to love him more than best friend, but how could she admit to him she loved him when Aiden assured her he would disappear from her forever if they crossed the boundary of their friendship?

She was always off limits. Until one forbidden summer, shy Elena surrendered to her brother’s best friend, the emotionally guarded Damien, in nights so hot they burned every rule to ash. Then he shattered her. Called their unborn child a bastard and walked away. Five years later, Damien comes face-to-face with the little boy who looks just like him… and the woman he never stopped craving. Now the man who runs from feelings must fight for the family he threw away. But Elena isn’t the timid girl he left behind and this time, she won’t make it easy.

"No Chris… you can't fucking kiss me with the same lips that tasted Anna's. You can't… just leave Chris, please leave…” She screamed, her body shaking terribly. For Anna coming home meant summer nights by the lake, her mother's cooking, and slipping back into the life she left behind. Most of all, it meant Carly, her best friend, her constant, her home. And Chris, Carly's boyfriend. Who was clearly off limits or at least... he should have been. Because the moment Anna steps back into Millbrook, something feels wrong. The town is quieter. The air feels heavier. And Chris? He isn't the same boy she remembers. He's colder, stronger and dangerous in a way that makes her heart race and her instincts scream. Then come the dreams. Running through moonlit fields. A voice calling her name. A presence she can't escape... or resist and when the truth finally surfaces, it shatters everything Anna thought she knew. Chris isn't just her best friend's boyfriend. He's an Alpha and impossibly she was his mate. Torn between loyalty and a bond she can't break, Anna must decide, walk away and protect the only family she's ever known or surrender to the Alpha who was never meant to be hers. Because in a town full of secrets, some fates are more dangerous than others... and loving him might cost her everything.

Gabriel Thorne was seventeen when he met his fated mate across a burning packhouse during a sanctioned werewolf purge. The moment their eyes locked, the mate bond snapped into place with devastating clarity. Dominic Ashford, the youngest billionaire Alpha in North America, rejected him instantly and publicly, shattering Gabriel's world with five brutal words: "I don't have a mate." Five years later, Gabriel has been cast out from the Holy Order, disowned by his exorcist family, and is barely surviving as a paranormal investigator when catastrophe strikes. His father is dying from a curse that can only be broken by Alpha blood willingly given. Gabriel must return to the pack territory he was exiled from and beg the mate who destroyed him for help. Dominic agrees, but his price is cruel: a thirty-day contract where Gabriel lives in his penthouse, attends pack functions as his companion, and submits to experimental mate bond suppression therapy designed to erase their connection forever. Gabriel accepts because he has no choice. Dominic believes proximity will kill the bond. Instead, it ignites into an inferno neither can control. As they're forced together, dangerous truths emerge. The curse killing Gabriel's father wasn't random, it was orchestrated. Someone inside the Holy Order is funding a conspiracy to restart the werewolf purges, and the scandalous mate bond between an exorcist heir and an Alpha is the spark that could ignite a supernatural war. Now Gabriel and Dominic must choose: break their bond to preserve the fragile peace, or claim each other and risk destroying everything their worlds have built. Their love could save both species, Or it could damn them all.
