Tessa Smith was born into the perfect life—wealth, fame, and love. As the only child of a renowned business tycoon and his elegant housewife, her days were filled with luxury, private tutors, and the unwavering belief that she would someday inherit her father’s empire. Groomed to be graceful, admired by fans, and adored by the media, Tessa's world seemed idyllic—until it shattered in a single, tragic moment. One fateful evening, masked intruders breached their heavily guarded island manor. Her mother, Kiera, answering the door with love and peace in her heart, was murdered in cold blood. That night rewrote Tessa's future. No longer driven by wealth or societal expectations, she chose a path that no one—least of all her father—had prepared her for: justice. Despite opposition, Tessa joined the force, quickly rising through the ranks as a brilliant, fearless detective. She cracked impossible cases and earned her place in a male-dominated world. Alongside her partner and love interest, Caleb Milanowski—a sharp-minded officer from humble beginnings—the duo formed an unstoppable team, both in investigations and in life. But just when they thought they’d found peace, a final case emerged: expose a powerful, faceless kingpin who had evaded justice for decades. Through riddles and coded messages, the truth led Tessa to a devastating revelation—one that would test her loyalty, threaten her relationship, and force her to choose between love, legacy, and the truth. In a gripping battle between duty and blood, Tessa is thrust into the heart of betrayal. To restore peace to a nation, she must dismantle the criminal empire that may be rooted in her very own family. A tale of love, loss, vengeance, and truth—where every secret comes with a price.

THE WOLF I FORGED TO LOVE ME - Mystery/Thriller novels & stories
Jay
Danielle Reyes-Callahan had one great love — and his name was Dante. From the moment he crossed a crowded fire to bring her a drink she hadn't asked for, she knew he was irreplaceable. They built a life together in the forests of the Pacific Northwest — a house, a future, dreams of children — until a violent November storm stole him in twenty minutes. He went out to protect their home and never came back. Fourteen months of grief nearly destroyed her. So she did the unthinkable. At an ancient forbidden ritual pool deep in the forest, Danielle performed the forging — pouring his wedding necklace, a strand of his hair, and every broken piece of her longing into the dark water. Something answered. What rose wore Dante's face perfectly. His voice. His smile. His memories. But it was not him. What she had forged was obsession wearing love's face — possessive, isolating, and darkening dangerously by the day. It threatened her family. It harmed the people she loved. And when it put its hands around Elena's wrist and looked at Danielle like she was something it owned rather than someone it loved — she finally faced the truth. She had not brought Dante home. She had built a monster. Now she must destroy it — surviving its attempt to kill her with her husband's own hands around her throat — and find the courage to finally let go. She kills it. And in the silence after, she begins — for the first time — to truly heal.

Enter Dragon Morales: New Orleans’ most notorious runaway, a cartel prince turned outlaw mechanic with grease-stained hands and a death wish. He doesn’t save people—he survives them. Yet in Dru’s lashed flesh and hellfire gaze, he sees his own shattered reflection. Their bond is gasoline and matches. Dragon’s father—Colombia’s cartel kingpin—hunts them relentlessly. Louise, armed with voodoo rites and the chaos-hungry loa Marinette, vows to break Dru. Their only allies? The Lou Nwa, a bayou biker gang trading in bullets and black magic, and Papa Legba, the crossroads spirit who offers Dru a lethal bargain: *“Her soul or yours.”* Fleeing through the Deep South’s cursed underbelly, they dodge cartel hitmen, haunted swamps, and safehouses reeking of betrayal.

But in the bayou’s choking heat, desire is a grenade they can’t outrun. This isn’t a fairytale. It’s switchblade kisses and saintly curses—a collision of fire and ruin where protectors become predators. Dru doesn’t need saving; she needs an inferno. And Dragon? He’s got a lighter and nothing left to burn. Will they raze the South to ashes, or become the sacrifice the crossroads demands? One truth remains: in the bayou, even survival leaves scars. **Warning:** No princes here. Just bayou smoke, blood-soaked magic, and the kind of love that devours.
