Buffy meets Supernatural in this high-tension, enemies-to-lovers paranormal romance. Discover a dark fantasy world of secret societies, demonic conspiracies, and the protective, nerdy scholar who falls first.

Thea was not a good girl. She was too loud, too opinionated, and far too stubborn to be adopted. But the Hildegard Sisterhood—a secret society of dangerous women—saw her potential. They took her in and other outcasts, training them as sanctioned Sinners: lethal, seductive assassins sworn to protect each other and reshape the world for the better.

They gave Thea a purpose, sisters, and an emotional sanctuary. But they also taught her she’d burn for every kill. In a world designed by men, these assassins don’t get Heaven, and they certainly don’t get happily ever afters.

They never really believed they’d burn... until real demons turned up and ruined everything.

Now they’re hunting hellspawn instead of human targets, barely keeping alive in a world on the brink of collapse. To make matters worse, an ancient prophecy claims these outcasts are the chosen ones fated to stop the apocalypse. And their rival demon hunters—the pious, all-male Team Saint—have just turned up on their doorstep demanding an alliance.

Lies.

They can’t be trusted. Thea can see it in their pretty-boy eyes. Wesley, their nerdy occult scholar, is the worst. He looks at her like she’s scum off his boots. But when a powerful demon possesses her beloved sister, and a sacred relic—an archangel’s staff—is the only cure, Thea is forced to accept Wesley’s help.

As their quest takes them across the world, danger and desire collide, and Thea and Wesley start relying on each other for more than survival.

But lies never stay buried for long, and when the truth finally surfaces, Thea is forced to do the unthinkable—choose between the only family she’s ever known and the man she was never supposed to love.

If only Thea were a good girl...

“Forgive me, Father … I killed a man.”

Why readers are in love with this dark paranormal romance:

• Enemies to Lovers & Forced Proximity: A lethal assassin and a nerdy professor-type scholar forced to work together to stop the apocalypse.
• The ‘He Falls First’ Nerd-Scholar MMC: Meet Wesley—your next favorite book boyfriend. Quiet, bookish, wears glasses, but possessive and fiercely protective when his girl is in danger.
• Unapologetic Badass FMC: Thea is a weapon-wielding assassin who doesn’t wait to be rescued (and isn’t afraid to protect her man).
• Found Family Sisterhood: Five dangerous, complicated women who will burn down the world for each other.
• Relic Hunt & Occult Lore: Packed with ancient prophecies, hidden archives, and Vatican conspiracies.
• The Emotional Payoff: A slow-burn, high-tension romance with witty banter and satisfying open-door heat.

If you love the nostalgic demon-hunting vibe of Buffy the Vampire Slayer, the grit of Supernatural, and the puzzle-solving suspense of The Da Vinci Code—but upgraded humor and mature, steamy romance like Lucifer—this series is your next binge-watch in book form.

Content & Maturity Note:

This dark romantic fantasy contains mature themes, high-stakes action/violence, and open-door romance. Recommended for readers 18+ who love their fantasy dark, their heroines dangerous, and their heroes devoted. HEA guaranteed.

Welcome to the Sinner Sisterhood, where stopping the apocalypse is just a standard Tuesday and the emotional baggage is heavier than the weaponry.

Consider this your heads-up for a delightfully toxic, high-stakes romance where "touch her and you die" is a divine promise backed by high-caliber artillery.

Expect to wade through your typical demonic dismemberment, casual crucifixion decor, and enough unholy bodily fluids and rotting flesh to make a dry-cleaner weep.

Our morally ambiguous cast boasts a glamorous cocktail of tragic orphanage backstories, dubious medical histories complete with asylum stints, and a penchant for self-flagellation.

Amidst the heavy grief, illnesses, and questionable substance-based coping mechanisms, you’ll find aggressively non-consensual demonic boundary-crossing that our heroines gladly stab their way out of.

But don't worry, the trauma is perfectly balanced by swoon-worthy hurt/comfort dynamics, like a hero gently washing away blood and bullet grazes in a highly emotionally charged shower scene, or an infuriatingly handsome nerdy enemy "accidentally" grabbing a handful of towel-wrapped breast while saving a heroine from a supernatural bird attack.

It all paves the way for highly explicit, graphic, on-page smut. Expect filthy dirty talk, relentless stamina, and toe-curling oral sex that breaks enough commandments to drag you straight to hell with a smile.
