Series numeration from Fantastic Fiction.

Mace Carson doesn't consider himself a hero. Back in college, he came upon a woman in trouble and intervened - but he was just one irate Wyoming cowboy with his boots planted firmly on the side of right. Now a successful vintner, Mace is shocked to be reunited with the woman he saved. But it turns out she's in Wyoming on business, a corporate executive representing the company that wants to buy his winery. Only, he's not selling. Kelly Wright has never forgotten that horrible night ten years ago when Mace came to her rescue, has never forgotten him. The surprising success of a winery in the middle of ranch country has brought her to Mustang Creek, and she's secretly thrilled to discover Mace at the helm. Reluctant to mix business with pleasure, Kelly vows to keep things professional, until her attacker is released from prison and comes for vengeance against both of them.
