He is dangerous, devoted and my dead husband's best friend, a lethal combination.

Widowhood has taken on a whole new meaning.

When I cashed Marco's first insurance check, I didn't expect it to matter. I mean any widow would have taken it; I was born to keep my daughter alive. I signed for a life-insurance payout, or so I thought.

But Nicolás Marchetti is definitely all man…the kind you dream of confessing your sins to in the dark.

The first year was bad. My rent paid itself and I'd catch men in dark suits outside my window doing something terrifying… and equally devoted.

The second year was worse, a stranger followed me home, vanished by morning and all hell broke loose.

On the third year, he showed up at my door in a black suit holding a wedding ring.

And by day four I had decided that I wanted the truth…all of it. Confessed….on his knees.

But ruthless, grieving Dons don't fall for widowed nurses. Or do they?

It's atmospheric mafia romance with a 4/5 spice level. Dark themes (mafia violence, on-page grief, controlled possessiveness). HEA guaranteed. If you read Cora Reilly, Skye Warren, Penelope Sky, or Rina Kent: Sworn is the same shelf.

🌶🌶🌶🌶 4/5. The slow burn earns every scene. First on-page intimacy lands around chapter 18; everything before that is touch starvation, forced proximity, single-bed-by-Marchetti-law, and a possessive hero who can barely breathe near her. When the slow burn breaks, it does not stop.

SWORN, catch mind

Meet the don who's been her shadow since the funeral.

Sofia Marchese writes Sworn from a tight dual first-person POV: Nicolás one chapter, Sofia the next. You will know what he's thinking before she does. You will hate him for what he's hiding. You will forgive him before she does. That's the design.

check fall for the man who broke every oath to keep her alive

SWORN, three minds

Three oaths bind one man's love.

Marco swore one at his wedding altar: to love and protect her until his last breath. Nicolás swore one at his best friend's deathbed: to provide for her, protect her, never let her know it's him. And there was the oath neither man ever spoke out loud: the one Nicolás made to himself the night he watched Marco propose to her, fifteen years before any of this began.

SWORN, three voices

Three secrets. One marriage. Every page.

Across 380 pages, Sworn traces how Nicolás Marchetti kept three impossible secrets, paid for them with fifteen years of silence, and lost the right to keep any of them when the war between the Five Families found her name:

check The oath at Marco's wedding: to never let himself say it.

check The oath at Marco's deathbed: to protect her at any cost.

check The oath he made to himself: to never let her know it was him.

check The Marchetti law that breaks all three at once: marry her, or watch her die.

One marriage. One week to confess fifteen years. One don who fell first and fell hardest.

SWORN, built like gift

    Stayed up until 4am.

    I started Friday night and stood up Saturday morning. I have not done that with a book in five years. Nicolás Marchetti is not a fictional man, he is a personality problem I now have.

    Best book husband I've read this year.

    The way Nicolás watches her at the funeral: that's the best "he fell first" I've ever read. He doesn't talk to her for three years and somehow you feel every conversation he doesn't have. Sofia Marchese knows what she's doing.

    Bought three copies before chapter 5.

    One for me, one for my sister, one for the friend who got me into mafia romance. We meet for coffee now to fight about whether Nicolás was right at the cathedral. That's the sign of a real book.

    Chapter 22 will be referenced for years.

    The cathedral scene is cinematic. I had to put the book down twice. Then I picked it back up and read until 3am. Sofia Marchese is in my top three this year and we're only in May.

    Brutal slow burn. Worth every page.

    I read more romance than my friends know. The slow burn here is brutal in the best way and Lucia is handled with more care than most adult heroines get. Pre-ordered Vow the moment I finished.

    Frequently Asked Questions

    Sworn is Book One of the Marchetti Oaths trilogy: a slow-burn mafia romance where the most ruthless don on the Eastern Seaboard has been protecting his best friend's widow in absolute silence for three years. When the war between the Five Families exposes her, the only way to save her life is to marry her under Marchetti law and confess every devoted, life-saving lie he has told her since the funeral. He fell first. He fell hardest. He kept it secret for fifteen years.

    Sworn is Book One of a trilogy. Each volume has a self-contained romance arc. Volume 1 (Sworn) resolves the Sofia / Nicolás central love story. Volume 2 (Vow) follows their first year of marriage and the family fallout. Volume 3 continues the Marchetti universe with a new central couple. You can stop after any volume: but you will not want to.

    Readers of Cora Reilly, Skye Warren, Penelope Sky, Rina Kent, and Sienna Snow. Anyone who lives for slow burn, forced proximity, possessive heroes, single-mother heroines, and HEA endings. If you cried at The Sweetest Oblivion, you will not survive Chapter 22 of Sworn unbothered.

    Atmospheric, not gratuitous. On-page mafia violence is controlled (off-page when it does not serve the story). The heroine's grief is real. The hero's possessiveness is intense but never crosses into the heroine. There is one explicit content warning for Chapter 28; it is flagged at the start of the chapter so you can skip if needed. HEA is guaranteed.

Approximately 380 pages, deckle-edge cream interior, dark sprayed edges, crimson silk-ribbon bookmark. Wrapped in a cream gift sleeve with the wax-seal motif. Hand-numbered. Free shipping in the US.
