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?

This isn’t a fantasy. It’s a reckoning. Of every boundary you swore you’d never cross. Of every secret you kept hidden behind polite smiles. Of the last fragile thread of hesitation you were clinging to. These aren’t gentle romances. They’re possessions.

You can’t stop. This is where innocence is tested in broad daylight. Where your best friend’s older brother corners you with words that leave you breathless. Where your married professor keeps you after class and blurs every line between teacher and temptation. Where your stepfather finally stops pretending… and claims what’s been his all along. They don’t ask. They take. They unravel you with dark eyes, commanding presence, and voices that turn your resistance into surrender. They’ll make you question everything. Make you feel things you never thought possible. You’ll feel guilty. You’ll feel exposed. You’ll feel alive. So keep the door locked. And baby? Be warned: this book doesn’t just linger in your mind. It changes you.
