Farming Love by Katherine Rose

Adam is spending the last of his trip to Germany in a small AirBnB with his dog. He just wants a quiet few weeks, and the horse farm seems like a good place to start.
That is, until Isabel, the daughter of his hosts, returns home from University. She is everything Adam has never wanted, but everything he needs.
Between his looming return to the United States and her parents’ disapproval, their relationship seems doomed to fail before it starts.
