Kingdom of Shadows. Dark Mafia Romance

I knew three days before the fire and I let it burn. That is the shape of what I did to Naomi, and no amount of the truth I told afterward, which was not much and not soon, could bend that line back straight. I am Preston Villalobos. I was Arlo's underboss, a made man in a kingdom built on other people's fear, and the one clean thing I ever had was a bladesmith with steel dust in her hair who did not care what I was.
When the family needed the money moved and the collateral gone, I chose the family. Her forge burned. Her father's last knife burned with it. She was hurt, and I told her it was random, because the truth would have sent her running, and I was not done being the man who got to keep her. She found the truth herself, in a logbook and a shell-company deed, and she took our daughter and disappeared into the hill country to build a life with a lock on the door. Now I have found them.
Naomi will not let me buy my way back, and she is right not to. She hands me a striker's hammer instead of forgiveness and lets me stand at her fire and sweat for nothing, and she watches, the way she reads a weld for the cold shut hiding inside it, the flaw that looks solid until the day it splits under load. She has already decided I am that flaw. I have to prove I am not, and there is no argument that does it, only the giving-up, piece by piece, of every part of the kingdom that made me worth fearing. So I gave it away.
The money, the name, the protection, the gun, the whole shadow-crown I bled for, until I was standing in her yard with empty hands and a daughter who did not know me and no reason on earth she should choose me except the true one. Some men rule from the dark. I had to walk out of it with nothing to deserve the woman who works in the light. A full-length, standalone dark mafia romance told entirely in the voice of the man who broke it, with a hidden child, a bladesmith heroine who keeps her spine, and a grovel that costs him everything he built.
