C is for Cowboy by Brenna Jacobs

When social media star Madi meets cute cowboy Cash, soon #romance is trending…
When Madi Keller escapes her mile-a-minute LA life to vacation at a ranch in the wilds of Montana, the last thing she has on her mind is handsome cowboys.
Cash Carter knows trouble when he sees it coming down the airport escalator—and it looks exactly like Madi Keller, right down to her overpriced designer cowboy boots and bright pink hat.
Soon Cash faces even more trouble than he bargained for when Madi turns out to have depth beneath her charm, and Madi might have to reevaluate her own cowboy prejudices when ranch life feels more appealing than a return to the city. When the differences between them are bigger than a star-filled Montana sky, can they put them aside to find the happiness they both desire?
