Two sisters. One empire built on a lie. And the man who made it all possible — still sitting at their mother's dinner table. Alessandra Marino has spent seventeen years building an empire in her father's name and calling it justice. She knows who killed him. She knows why. She has been moving toward the reckoning in a straight line since she was old enough to hold a weapon. She doesn't know about Mara. When a dying enemy hands her the truth she never wanted — that her father had a second daughter, that Accardi has been watching that daughter her entire life, that the clock is already running out — Alessandra's seventeen-year war stops being simple. Because protecting Mara means finding her first. And finding Mara means forcing a stranger to look at the rubble of her life and decide whether to run or fight. Blood doesn't make a family. But fire might. Black Suit and Broken Oath is a 150,000-word dark mafia thriller about power, sisterhood, and the kind of revenge that doesn't look like what you thought it would when you finally get there.
