My Cowboy Best Man Bachelor by Hanna Hart

Violet Kirschner never would have thought that she’d have to pick between her family and her ultimate childhood crush, Holden.

Cowboy Billionaire Holden Hayes seems to be nothing but trouble. As the owner of a wildly successful ranch in Little Valley, Texas, he has the reputation of being a heartbreaker. But there’s more to him than what meets the eye.
Holden is saving himself for marriage, which wouldn’t matter if he can’t be with the woman that he’s in love with.
His best friend’s little sister.
Violet is off limits. Her brother, Vince, is overprotective of her. The only way for them to be together is if they do so secretly. But how long can this secret stay hidden before the entire town finds out about it?
