Nadia Voss is a broke hotel maid who takes a wrong elevator and walks into the private penthouse of Callum Ashford — the coldest, most powerful man in the city — and sees something she was never meant to see. His offer is simple: six weeks pretending to be his girlfriend, a life inside his tower, and enough money to save her sick mother's life. But the higher she rises into Callum's world, the more she suspects the secret she stumbled into is only the surface of something far darker — and that the scarred man who watched her from across that glass table with the flat patience of someone who handles problems hasn't forgotten her face. Callum is controlled, careful, and impossible to read, and every moment she spends close to him makes it harder to remember that she's only there because he needed her silent. The question isn't whether Nadia can play the part — it's whether she'll still want to walk away when the six weeks are up, or whether the most dangerous thing in the building will turn out to be what she's starting to feel.
