“She survived war.She was betrayed at home.She married the most dangerous man alive. When former Army Captain Ava Blackwood discovers that the man she loved-and secretly built an empire for-has been sleeping with her stepsister, she does not beg, confront, or break down. She walks away. Bound by a ruthless inheritance clause that demands marriage before her twenty-eighth birthday, Ava enters a flash marriage with Lucien Drake-the billionaire CEO she once saved on a classified battlefield mission. What the world doesn't know is that Lucien is not just a businessman. He is the King of the Underworld. As enemies close in and blood debts resurface, Ava returns to the only life she ever trusted-war. But this time, the battlefield is made of boardrooms, crime syndicates, and vows signed in fire.”
