Chasing Christmas by Shanna Hatfield

He certainly didn’t ask Santa for a bride. . .
Dragged into a crazy publicity stunt, one handsome cowboy has no idea how he ended up accidentally married.

Professional bull rider Chase Jarrett has the world on a string. The only blight in his idyllic existence is his nosy cousin’s nonstop nagging about his need for more publicity. Tired of listening to her suggestions, he gives her free rein when she hatches a plan to skyrocket his popularity. All he has to do is show up for a phony wedding in Las Vegas. Then Chase discovers the wedding was real, the surprise bride is beautiful, and his sponsors are demanding he remain married.
Shy and introverted, the last thing Jessie Pierce wants is to find herself in the spotlight. But thanks to a meddling so-called best friend, that’s exactly where she’s at. The promise of an all-expenses paid vacation to Las Vegas lures her on an adventure that ends with her unexpectedly married to a hunky bull rider who would draw her out of her shell if she’d let him.
A business proposal leaves the two of them committed to a year of marriage. How hard could it be to remain wed in name only?
