In Siobhan Davis’s dark mafia romance, , Sierra and Bennett’s relationship is defined by a decade of secrets, unrequited longing, and the violent legacy of the Mazzone crime family.

He took a step into the light, his eyes dark and hungry. He was the underboss now, a man who ruled through fear. Loving him was a death sentence; staying away was impossible. In this world, we were condemned long before we ever had a chance to choose each other.

I clutched my secrets closer to my heart, the weight of everything I hadn’t told him—the baby, the years of running—threatening to pull me under. "I didn't have a choice, Ben. I'm a pawn in a game I never asked to play."

The man standing before me wasn't the boy who used to call me "Firefly." Bennett Mazzone had been my sister’s boyfriend, the one person who looked at me and saw something worth protecting when the rest of the world saw a ghost. But that boy had died ten years ago, replaced by a cold, calculating killer with hands stained by the very blood he was sworn to protect me from.

Forbidden love, secret pregnancy, second chances, and the violent power struggles of the Italian mob.

"You shouldn't have come back, Sierra," he said, his voice a gravelly warning that vibrated in my chest.
