Is 'If She Only Knew' Book A Thriller?

She married him knowing one thing clearly: love was never part of the agreement. Their marriage was built on terms, not promises. A shared home. A shared bed. A public image to maintain. Nothing more. He was distant, controlled, and never cruel — but never warm either. To him, she was a wife in name, a solution to a problem, a role that needed to be filled. What neither of them expected was how silence could become dangerous. How intimacy without love could still leave marks. How wanting someone could come long before admitting it. As the line between obligation and desire begins to blur, she must decide how long she can stay where she isn’t truly chosen — and he must face the truth he never planned for. Because sometimes, the most dangerous thing isn’t loving someone too much… It’s realizing you never meant to love them at all.
