This author once failed as a heroine… and returned as something entirely different. Not as a savior. But as the villain. And she didn’t come back empty-handed. She brought secrets. She brought sins. She brought a story that was never meant to be read. Sinners & Saints is not just a collection of dark romance stories— It is a confession. A warning. And a door best left unopened. Within these pages lie twisted love stories where desire and destruction walk hand in hand, and every choice comes with a cost. So the question is simple: Will you turn away… or step inside anyway?

I'm a half-baked forensic examiner whose only redeeming quality is the ability to understand animals. The crime scene is inside a lavish villa. The lady of the house lies dead on the floor with a blunt-force injury to the back of her head so deep that her bone is visible. The safe has been pried open, and a million dollars in cash has vanished without a trace. Clear shoe prints mark the backyard wall, evidence that someone has climbed over it. "This one's clear as day. This is a textbook robbery-homicide. The suspect is likely a young male, around six feet tall, has a prior theft record, and knows how to cover his tracks. Check the surveillance footage in the area and look into places where he might've moved the stolen cash." The director of the forensic science center, Egbert Woodward, has been in the profession for three decades and is a widely respected authority. The officers at the scene nod in unison and begin taking notes. I'm the only one who stares at the 30 flies circling the ceiling for a full 3 minutes before taking a step forward and piping up, "Dr. Woodward, this isn't a robbery-homicide. It's a crime of passion. The murderer is the victim's husband!"

All it took was a gunshot to have this criminal fucking me senseless. I'd spent months trying to bring down Antonio, the criminal I swore to put behind bars. I even set a trap for him, using someone close as bait. But instead of going down in chains, Antonio offered himself to me, in exchange for freedom. I should have said no, I should have followed the mission. But as a lonely divorcee craving warmth, how could I resist the way he touched me? The way his fingers made me forget the rules I live by? This wasn't the plan. My boss didn't send me here to get addicted to my enemy. Yet every secret night with Antonio leaves me wanting more, and drags me deeper into his dangerous world. He's supposed to die for his crimes, but unfortunately, the real crime is how badly I want him. And if the news gets out, I won't just lose my job– I'll lose my life.
