Penthouse Prison

PENTHOUSE PRISON

A Dark Mafia Romance

Standalone with Series Potential  •  Dual First Person POV  •  HEA

When a debt collector’s daughter is locked in a ruthless mafia boss’s penthouse as collateral for her father’s betrayal, she discovers the most dangerous thing in her gilded cage isn’t the man who put her there—it’s how much she wants to stay.

Sienna Moretti has spent her entire life trying to outrun her father’s gambling debts and connections to the criminal underworld. A trauma nurse working double shifts in Boston, she’s finally clawing her way toward freedom—until the night Dominik Valeri’s men drag her from her apartment and deliver her to the top floor of Valeri Tower.

The most feared boss in the Northeast syndicate doesn’t want her money. He wants leverage. Her father stole something worth more than cash from the Valeri family, and until it’s returned, Sienna is collateral—a prisoner in a penthouse dripping with neon city lights and cold, calculated luxury.

Dominik is everything Sienna despises: ruthless, controlling, and utterly unrepentant about the empire he rules with an iron fist. But behind the three-piece suits and veiled threats is a man carrying scars that mirror her own—a man who flinches when she tends his wounds, who watches her sleep from across the room like she’s something sacred and breakable.

As days bleed into weeks, the walls between captor and captive begin to fracture. Sienna sees the fractured boy beneath the monster, and Dominik discovers that the woman he took to punish her father might be the only person who’s ever looked at him and not been afraid. But when the truth about her father’s theft surfaces—and it’s far darker than either of them imagined—Sienna must decide whether the man who locked her away is the villain of her story, or the one person willing to burn the world down to keep her safe.
