Five years ago, Vivienne Ashford, the city's coolly elegant, standoffish horse trainer, fell for a delivery driver. Every rich, beautiful socialite who used to fawn over her was beside herself. Five years later, Vivienne finally learned that her delivery-driver boyfriend had been playing her the whole time. The delivery job was nothing but a disguise. In truth, he was Roman Sinclair, president of Sinclair Group's Asia-Pacific division. The future head of the entire Sinclair dynasty. And the only reason Roman had ever chased her in the first place was a 50 million dollar bet with his buddy Knox. Once she knew the whole truth, Vivienne walked away and took over her family's vast grasslands. Back then, because Roman had worried they came from different worlds, she'd never told him the truth: that she was the sole heir to a hundred-billion-dollar ranching empire, with well over a thousand ranches to her name.
