Her Billionaire Cowboy by Liz Isaacson

HE BOUGHT HER FARM, AND SHE’S NOT HAPPY ABOUT IT.
Tucker Jenkins has had enough of tall buildings, traffic, and business meetings to determine the next app that will change the world. He’s sold his technology firm for billions and traded it for Steeple Ridge Horse Farm in rural Vermont.
Missy Marino has worked at the boarding stable and farm since she was a teen, and she’s always dreamed of owning it. But her ex-husband left her with a truckload of debt, making her fantasies of owning the farm unfulfilled.
When she meets Tucker, she starts having a new kind of fantasy—one where they work with the horses together. Tucker didn’t come to the country to find a new wife, but he supposes a woman could help him start over in Steeple Ridge. Will Tucker and Missy be able to navigate the shaky ground between them to find a new beginning?
