Probst, Jennifer. Stay series.

"Happily single, Harper Bishop trusts in only one passion - her rescue farm and healing her thoroughbred, Phoenix. Her dream is to lead him to the Triple Crown. But how unreachable is it without experience or help? A handsome new guest at her family's B&B has what it takes to make it come true. And with his irresistible brogue, warm smile, and soothing touch, he's a major distraction. After a bitter betrayal, horse trainer Aidan O'Connor has fled Ireland for a vacation in New York's Hudson Valley. When he sees the horse with the fighting spirit, he's inspired with a new goal: to train Phoenix to win. He's also facing an unexpected new challenge: his feelings for Harper. How can she dare to open her heart to a man who'll be there only long enough to break it? So Harper and Aidan agree: try to keep it professional, and focus only on Phoenix and the finish line. But along the way, they could also learn a few lessons in love, trust, and taking chances. And, as painful as it promises to be, saying goodbye." --
