*Falling for a mafia billionaire heir wasn’t in Sienna Sinclair’s plan. Neither was discovering that her new job is a front for organized crime, or that the mysterious elevator in her office building holds a mystery of its own. Cassius Moretti has spent his life trying to escape his family’s legacy. But when Sienna stumbles into his world—beautiful, intelligent, and dangerously curious—he realizes some things are worth fighting for. Even if it means war unless it’s for her and her only. Caught between two warring crime families, with a building that defies logic and a mother’s secrets rising from the grave, Sienna must decide: trust the man she’s falling for, or save herself from a world where love and death are intertwined.
