The Devil's Covenant

They buried my father on a Monday. By Friday morning I was married to the man who let him die. Saoirse Brennan learned to count money before she learned to pray. She has kept her father's books since she was twenty-two, and she has never once been wrong about a number. Then two rounds put him in the ground outside his own bar, her uncle sells the family's last piece of the waterfront out from under his grave, and every man in South Boston starts waiting to see how long a twenty-five-year-old girl lasts.
Declan Kearney owns half the paper in this city and every room he walks into. He is thirty-eight, Irish to the bone, and the last man alive who ever heard Michael Brennan say no. He wants the berth. He wants the Brennan name standing beside his own. And he has wanted her since long before she needed him. So he names his terms. She keeps the berth. He keeps the name. Her brother comes into his house.
Whatever happens to her uncle, she is in the room. And he does not touch her. The rules last about as long as you would expect. But somebody wanted her father dead, and it was not her uncle, and it was not the family from Providence. Somebody has been buying pieces of this waterfront for two years without ever once saying a sentence out loud. And when Saoirse finally opens the box her husband has never opened, she is going to find a name in her own father's handwriting and a debt thirty years old that neither family has ever been able to pay.
He can burn every man who comes for her. He cannot give her back the one she buried. To keep her, the man whose word ends every argument will have to hand the last word to someone else. You can sign a covenant with the devil. You cannot sign one with your own heart. A dark, slow-burn Irish mafia romance featuring an arranged marriage, enemies to lovers, forced proximity, a possessive morally gray anti-hero, a heroine with teeth, and a guaranteed happily ever after.
Standalone. No cliffhanger. No cheating. Dual first-person POV. This is a dark romance: on-page violence, explicit content, and grief. Content warnings inside the front matter. He married her to take a door. She married him to keep one shut.
