On the night of her engagement party, Esther York watches five years of her life end in thirty seconds. Her fiancé dives into the pool — not for her, but for her stepsister. In front of two hundred people. On camera.

She walks out alone. She finds a park bench. And she finds a stranger in the dark who is also soaking wet, who says me neither when she tells him she is not all right — and who, she will learn later, was in the water before her fiancé was. Reaching for her. When nobody was watching.

His name is Ricky. She proposes to him at dawn.

It is, she tells herself, a practical arrangement. A legal solution. One year, clean terms, no complications. She needs a husband to inherit her mother's company. He needs a reason to stop hiding his name — because Ricky is also Frederick Patterson, billionaire heir and CEO, who has been waiting his whole life for someone to want him without knowing who he was.

She proposed to Ricky. That distinction is the foundation of everything they build.

But foundations get tested. Her stepfather is moving against her mother's legacy. Her stepsister wants what belongs to her. And somewhere behind a wardrobe full of winter coats, a green cloth journal holds the truth about how her mother really died — written in her mother's own hand, waiting to be found.

When Nobody Was Watching is a slow-burn romance about a woman who stopped organizing herself away from the things she wanted, a man who stopped hiding the truest version of himself, and the love that grew between them before either of them thought to name it.

One park bench. One proposal. One arrangement that was never going to stay practical.
