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 quit and dipped. City threw a parade. Only Jenna Blake—my oh-so-gifted junior who claimed she could "see through killers' eyes"—lost it. At her celebration banquet, she went full drama queen: "I owe everything to Kate Mercer. Please, bring her back!" I laughed. Cold. Not happening. Last time around, I was the hotshot detective. But every clue I found? She dropped it first like she read my mind. People started saying I was washed. So I went all in—three months, no sleep, cracked a massive trafficking ring. Led the raid myself. She beat me there. Again. Place was cleaned out. Boom. She's the city's golden girl. I'm the clown with no game. Pressure got ugly. My head snapped.

Special Agent Violet (sometimes Secret Agent Violet) is one of the FBI's best agents. She's very good at deducing people and observing things most people missed. She's socially inept with no friends. She's very dedicated and loves her work...so much. The word love is alien to her. Relationships were nothing for her. She just needs work, work, work, and work. Her heart was stone-cold.
