Priest Series Deep Dive: Sierra Simone’s Forbidden Masterpiece

If forbidden romance had a holy text, Sierra Simone’s Priest series would be the first book on the altar. It is scandalous, lyrical, and unapologetically hot. Each story in this quartet mixes sin and salvation in a way that leaves readers both blushing and spiritually confused in the best possible way.
Many people search for the Priest book series in order, so here it is: Priest, Midnight Mass, Sinner, and Saint. Each book focuses on a different Bell brother and their struggle with faith, desire, and the kind of love that is absolutely not covered in Sunday school. Reading them in sequence delivers the full emotional arc of the Bell family and their signature mix of guilt and pleasure.
These books became a viral sensation on BookTok because they are not just spicy, they are thoughtful, messy, and human. You will not find any soft fade-to-black scenes here. Sierra Simone takes taboo topics and turns them into art that feels both blasphemous and beautiful.

Reading the Priest Series in Order
If you want the full experience, this is the best order to read them:
- Priest
- Midnight Mass (Novella)
- Sinner
- Saint
Reading them in sequence gives you the proper emotional timeline of the Bell brothers and their tangled connection to faith, love, and redemption.
Priest (Book 1)
Tropes: Forbidden love, priest/penitent, redemption through desire
Spice rating: 🌶️🌶️🌶️🌶️+
Why it fits: Priest is the book that started the fire. Father Bell breaks his vows for a woman who comes to him for confession, and readers have been scandalized ever since. The writing is elegant, emotional, and almost poetic. This is not your average taboo romance. It is a story that makes you think about what it means to want something you should never touch. BookTok readers still whisper, “Bless me, Father, for I have reread.”
Midnight Mass (Book 1.5, Novella)
Tropes: Marriage in crisis, forbidden love aftermath, emotional angst
Spice rating: 🌶️🌶️🌶️
Why it fits: While most forbidden romances end on a high note, Midnight Mass digs into what happens after the fall. It’s a short but devastatingly intimate continuation of Father Bell’s story, where guilt, secrecy, and desire clash in haunting ways. This novella is pure emotional penance, and fans say it hurts in all the right places.
Sinner (Book 2)
Tropes: Forbidden love, nun heroine, grumpy/sunshine, crisis of faith
Spice rating: 🌶️🌶️🌶️🌶️+
Why it fits: Sinner swaps the priest collar for a nun’s habit. Sean Bell, the confident golden boy brother, falls for a woman preparing to take her vows. Their chemistry is electric, the tension unbearable, and the result is pure chaos. Readers love it for the emotional depth and the audacity of its premise. Sinner dares you to look away, and you absolutely cannot. It’s raw, addictive, and utterly shameless in the best way. BookTok calls it “the reason I side-eye every habit I see.” If Priest shocked you, Sinner will make you question everything.
Saint (Book 3)
Tropes: Monk MMC, second chances, forbidden love, faith vs. passion
Spice rating: 🌶️🌶️🌶️
Why it fits: Aiden Bell, the quietest, most tortured of the Bell brothers, becomes a monk, running from a love he couldn’t handle. Saint takes the series’ signature taboo and turns it inward, exploring the ache between duty and desire. It’s softer, more emotional, and profoundly moving. Readers call it “a spiritual experience with spice.” If Priest was sin and Sinner was temptation, Saint is redemption.
Why Readers Can’t Quit the Priest Series
The Priest universe hits a rare sweet spot between literary and filthy. Simone doesn’t write cheap shock value; she writes about the beauty and horror of desire, what it means to want something that could destroy you. That’s why BookTok, Bookstagram, and the spicier corners of Reddit still won’t shut up about it.
Every Bell brother’s story dives into a different shade of sin: lust, pride, guilt, and atonement. Together, they form one of the boldest and most addictive romance series of the decade.
Creature Comforts: Go In Peace (and Maybe Sin a Little)
Sierra Simone’s Priest series isn’t just spicy, it’s spiritual chaos with a body count of broken morals. It’s the kind of romance that makes you want to pray and blush at the same time.
So whether you’re here for the forbidden vows, the emotional wreckage, or just the promise of a priest who really knows confession, you’re in for something unforgettable. Go forth, read boldly, and may your Kindle survive the heat.
