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

Who is this book for?
Who is this book for?
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.
How dark is it?
How dark is it?
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.
