The Best-Friend Billionaire Cowboy: Zack by Bonnie R. Paulson

Her brother’s best-friend and a decade-old crush – both have grown into something tumultuous.
Julianna Johnson is back home for her daddy’s funeral in Clearwater County, Montana. Love is in the air from a recent wedding and she’s close to screaming. She’s sworn off men and anything resembling love or longing when Zack Brough rides back into her life – on her worst day yet.
Zack doesn’t have a choice on attending the Johnson funeral. Julianna’s brother is his best-friend and funerals are something best-friends go to. But when he sees Julianna, all he can think about is how long it took his heart to heal the last time she left town.
Luckily, he has money and he’s jaded from a bad divorce – so there’s no danger of falling for her… or anyone… again.
Except… Julianna is sass and fire and everything he’s ever wanted. Zack can’t stop longing for what might have been – what could have been.
Just when he thinks there’s no chance he can love again, he’s thrown into close proximity with Julianna again and he realizes she’s the reason he can’t be happy with anyone else.
He can’t just give up on what could be. Zack might have the last chance he’ll ever get to convince Julianna they’re worth trying for. If they can’t work things out before they return to their lives, Zack fears his last chance at love will ride into the sunset.
