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?

To save the merfolk from slaughter, I seduced the vampire lord himself-Lazarus. He still loved me after all. For three days and three nights, he drowned himself in my body, unwilling to let me out of his arms for even a second. I roused from the haze of fleeting bliss, only to have a searing, corrosive liquid poured mercilessly over my head. "You with eternal healing can taste the sting of agony？" "Yet your trivial suffering pales in comparison to the loss of my kin you brought upon me. It is nothing at all!" "This is merely the beginning. Refuse to reveal where my parents lie hidden, and you shall never break free from this castle." He was convinced that I alone had destroyed everything he held dear. Holding the entire merfolk’s lives hostage, he confined me within the castle. Time and again, he tore open my chest by force, wrenching out my pearl of the mer, feeding its essence to Isolde to mend her frail flesh. He condemned me to sleepless nights, forcing me to cleanse the filth he left behind. Barefoot, I was made to dance the mermaid’s lament upon razor-sharp silver blades, writhing in pain to lull Isolde into slumber. Later, Isolde feigned a pregnancy. Driven by false tenderness for her, Lazarus took to slicing chunks of my immortal mermaid flesh with cold blades, brewing them into nourishing potions for her. Hatred for me burned deep in his bones, yet whenever I was on the brink of death, he would still force his own blood down my throat to keep me alive. "You presume too much on my lingering love for you, choosing silence over the truth, do you not? Aurora… tell me, what became of my parents?" I endured in silence, bearing witness to his love torn between hatred and longing. Soon, I would no longer need to guard that fatal secret. For a mermaid who dwells on land for three years shall wither and perish, severed from the sea that gives her life. Only three days remained until my final breath.

The sirens knew how to do only one thing. Kill. Usually, it was just those who travelled their seas, until the greedy ruler of Greake, captured their queen. The sirens ventured into the lands at midnight in search of their Queen, bringing chaos along with them. So many lives were lost from the midnight invasion, as such the humans had a powerful witch, Adora, summon the Pombero to keep the sirens off their lands. King Edwardo got greedy again.
