Outside a glittering party, I saw a man in the dark. I didn’t know then that he was an assassin. A hit man. A mercenary. Ronan radiated danger and beauty. Mercy and mystery. I wanted him, but I was already promised to another man. Ronan might be the one who murdered him. But two warring families want my blood. I don’t know where to turn. In a mad world of luxury and secrets, he’s the only one I can trust.

Ronan. His name thrums through me like a heartbeat. I climbed out of the smoldering crater of my life only to find myself back in the middle of a slow-motion trainwreck. I’m hunted, torn between my past and present, ripped apart by two warring families. My husband is dead, and his killer is the only man who’s ever felt the deep well of emotion I keep hidden from the world. Ronan. Vicious and scarred—his rough touch is seared into my skin, but his soft caresses are what break down my walls bit by bit. Until there’s only me left. My soul in his bloody hands, and my broken heart beating just for him. Only him. Ronan. My shadowy protector, my phantom lover—kiss me or kill me, I don’t care. As long as you’re the one who does it.

Marriage has always meant violence. I don’t trust it, but it’s the only thing keeping me afloat in these dark undercurrents. I married for safety but I got the most dangerous thing in the world—Ronan Byrne for a husband. Now we’re returning to Bishop’s Landing to face our demons. Mine. His. We have real enemies to conquer, but it’s the fear in my heart that beats the loudest. I can’t stop being in love with him. Except the killer with the heart of stone doesn’t love me. I don’t know whose family I belong in anymore. Or whether I should stay with Ronan when this is over. But I may not live long enough to make the choice.
