I'm looking for a romance novel with a strong business or billionaire element, perhaps involving a contract marriage trope.

If you're interested in a romance novel with a billionaire character and a contract marriage trope, "TGLES #1 - BLACK & RED" appears to be a fitting choice. The description explicitly mentions Xander Redent as a "wealthy playboy heir" and Athena Lemiere as a "brilliant mechanic," setting up a classic dynamic between different social strata. The mention of their families' "business alliance" strongly suggests a scenario where their union might be more than just a romantic connection, hinting at a contract or arranged marriage for strategic purposes.

The description also sparks interest by stating they were "destined to clash" but ignited a "passion," which is a hallmark of many engaging romance novels where initial conflict evolves into genuine attraction. This kind of story often plays on the tension between obligation and desire, exploring how two individuals who might not have otherwise met or connected are brought together by external circumstances and eventually find love. The billionaire aspect adds an element of luxury, power dynamics, and potentially a world of high society that can be both alluring and a source of conflict within the romance.
