Training the Heart by Paisley Hope

Wade Ashby is a closed book.

With the weight of the family business on his shoulders, and his ongoing battle to escape a failed marriage, he only has time for one thing: looking after his ranch.
Life has dealt Ivy Spencer some tough blows.
So when the opportunity to work on the Silver Pines ranch presents itself, she grabs it by the horns. Nothing will stand in the way of her dream of training a racehorse on route to the Kentucky Derby.
Wade might be determined to keep his heart under lock and key, but Ivy’s constant presence soon ignites a passion he thought he’d lost long ago.
And once she starts tearing down his walls, there’s no going back. . .
Because the only way he’ll open up his heart again is if it stays that way forever.
