Cardin Worth is ready to tune up her engine—with Trey, her former crush! However, he's a Davis—one of her car-racing family's bitter rivals. But she might be able to create peace, and also get some sizzling sex on the side… …if Trey pretends to be her fiancé, that is! Having a little fun on those steamy Southern nights seems like a great idea. Just to patch up the feud, of course. Then Trey'll be leaving town again—this time for good. But Cardin's not sure she can relinquish the superheated sex…because Trey's the most talented, uh, mechanic to ever look under her hood!
