Castellano's Vow: A Dark Mafia Billionaire Romance (Castellano Empire - A Dark Mafia Romance Trilogy)

He sent her away to keep her alive. He never told her why.

Dante Castellano is the brother the family points at when something has to disappear. Thirty-nine years old, six-three, the second of four Castellano sons and the one who keeps the family's empire intact when polite power isn't enough. Last winter a Marchetti arson left him with second-degree burns across his left forearm and a debt he intends to collect in full. He runs the inside-source hunt because no one else can stomach what it costs. He has not let himself want anything in eight years.

Beatrice Gallo is thirty-four. A forensic linguist in a Brooklyn lab — the kind of woman who can identify a man's province from how he writes his contracts. Once, she was an FBI analyst on the Castellano surveillance squad. Once, she spent six months being a name Dante said in the dark. In October 2018 her section chief sat her down and told her the affair she had never breathed a word of to anyone had been discovered. She resigned the next day. She has not spoken his name aloud since.

When Dante walks into her lab to tell her a Marchetti capo has put her in his sights, and that her files prove the two crime families are sharing a legal drafter neither admits to, she has thirty seconds to decide whether to run from the only people who know what she really is, or get in the car.

What he doesn't know: she has held the name of the man who burned her in 2018 for eight years. What she doesn't know: the man who burned her wasn't the FBI. The leak was inside his family. The proof has been on her desk all along.

When the woman you let go to save her is the only one who can finish the war you started — what do you owe her?

For readers of Cora Reilly, Rina Kent, Ana Huang, Penelope Douglas, Alta Hensley (Sovranos), Danielle Lori, K.C. Crowne, and Vanessa Vale.

Content note: explicit sexual content, on-page violence (mafia rivalry, arson aftermath, threat scenes), morally dark hero who orchestrates violence, surveillance and forced-proximity dynamics, federal-investigation tension, eight-year separation grief processed on-page, dead-relationship-by-coercion backstory. No SA of the FMC, no cheating, no OW/OM drama. HEA unambiguous. Dark romance readers are not punished with ambiguous endings.
