Four spouses. One experiment. Every private choice becomes evidence. Madison Cole enters Meridian House hoping a radical thirty-day marriage experiment will finally reveal whether her relationship with Ethan can be saved. The rules appear simple: two married couples, algorithmically selected partners, complete honesty, and the freedom to explore a connection outside their marriages. Madison is paired with Theo Grant - while their spouses are matched with each other. The attraction between Madison and Theo is immediate, unexpected, and entirely consensual. But as emotional boundaries dissolve and desire becomes harder to resist, Madison discovers that Meridian House is measuring far more than compatibility. Hidden cameras are recording their private moments. Psychological scores are manipulating their decisions. And someone has engineered the experiment to destroy Madison's reputation, steal her company, and replace her before she can object. To escape, Madison and Theo must expose the people controlling the experiment without allowing their genuine connection to become another weapon used against them. A provocative romantic suspense novel about forbidden attraction, marital betrayal, privacy, consent, and the difference between being perfectly matched and freely chosen.
