The Compelling Cowboy by Keira K. Barton

Brenda Firestone is in command of the family ranch, and her life. She’s determined to have total control over her destiny, which means she’s adamantly opposed to falling in love. Desperate for a new ranch foreman, Brenda invites an old flame to come fill the position, and that’s when her plan starts to unravel.
Justin Beckstead has been in love with Brenda for almost half of his life. When she asks him to come to Colorado to work on her family’s ranch, he accepts right away—excited about their reunion. When he and Brenda can’t agree on how to proceed with their relationship, the end seems near.
Will Justin be able to convince Brenda that she should gamble her predictable life on him? Or will Brenda resist the magnetism that’s always existed between them and leave Justin to wonder what could have been once more?
