In the shadows of New York City, vows are written in blood.
Isabella Romano has spent her life outrunning the sins of her family. Quiet, disciplined, invisible-exactly how she likes it. But when her father's debt lands her at the mercy of the city's most feared don, escape is no longer an option.
Lucien Moretti doesn't grant mercy. He collects.
Cold, brilliant, and devastatingly controlled, Lucien rules his empire with iron logic and ruthless consequence. Taking Isabella as collateral should be simple business.
It isn't.
Because the girl who was supposed to be leverage becomes temptation.
And in a world where love is a weakness, wanting her might be the one mistake that destroys them both.
Possession turns to obsession.
Protection turns to war.
And the vows binding them may demand the ultimate sacrifice.
