His Beautiful Ruin: A Dark Billionaire Protector Romance

She restores buildings for a living. He built an empire by predicting everything that could go wrong. Neither of them is prepared for a threat designed to predict them both. Architect Eva Serrano is nine days from reopening Halcyon House when someone uploads a falsified structural drawing under her credentials - a change that could have turned a charity gala into a mass-casualty event. Embedded inside the sabotage is something worse: a behavioral forecast describing exactly how Eva will react and exactly how billionaire security strategist Nikolai Soren will try to control the danger around her. Nikolai has spent his adult life making uncertainty smaller. He owns one of the most powerful private-security and cyber-intelligence firms in Europe, and Project Janus once learned from systems his company helped build. Protecting Eva should be simple. She refuses to let it be. Every safeguard must be negotiated. Every camera needs a reason. Every boundary has to survive the fact that someone is actively studying them. As Eva and Nikolai uncover a hidden intelligence room beneath Halcyon House, attraction becomes impossible to separate from the investigation. Then Nikolai crosses the line he promised he would respect: he secretly expands surveillance around Eva without her consent. The threat may justify fear. It does not justify ownership. To have any chance of earning Eva back, Nikolai must surrender unilateral authority over the system that made him powerful, submit his own company to independent oversight, and learn that safety without choice is only another kind of cage. His Beautiful Ruin is Book 3 of The Sable Consortium, an interconnected dark billionaire romantic-suspense series. It features forced proximity, billionaire-protector tension, a brilliant architect heroine, negotiated protection, surveillance ethics, explicit consent, corporate conspiracy, and a complete romantic HEA.
